I've been living in Rialto for almost 2 years. There is a community/cluster mail box for half the block and just come to find out that is gone. Yes gone! When I first moved in it was broken into and for almost a year had to go to the post office to pick up my mail. I was not told it was broken into nor that mail was not being delivered I just found out when I noticed I was not receiving any mail. It took the Post office forever to fix it (its not an HOA community) and they even sent a letter stating that they would no longer hold my mail if I didn't fix my mail box. Again the Post office responsibility to fix it. When I went to pick up my mail I found out it was gone. This is was my tax dollars are going towards?! Bad services, no communication, no urgency! Its a small city and there's so many things wrong with it.

I am getting bulk mail back from the post office saying there is no receptacle in place. These are homes as well as complexes after speaking to the parents there are mailboxes and the mail person has access to most.

My old mailman put the lock on my mailbox everyday. We have some new mail lady and she refused to lock my mailbox. My mail is being stolen, I've already had identity fraud in the past because of mail theft. I asked her if she could put the lock on after she opened the box and the lock fell on the ground. She replied she already confirmed with her supervisor she didn't have to. Had a huge attitude and yesterday I watched her on camera cramming my mail in the box 3 times to crush and tear it. Is this how the rialto post office behaves? This is absolutely ridiculous and not called for. If she doesn't want to do her job fire her, she is useless and a drain on society. Oh yeah, she left the lock on the ground as a trip Hazzard, again being useless.

I have lived in my home for 31 years and have never had a problem with my mail delivery. Recently, a van has been abandoned in front of my house and the mailman has not left our mail for days. He has not left a note regarding the situation. My husband was in the front yard and the mailman drove past him. We have contacted the proper authorities to have the van moved. We have important mail that needs to be delivered. This is how the USPS treats it customers....shameful.

I would sincerely appreciate it if you would pay attend the when the time changes. It happens twice a year. Each time this happens tú forget to make whatever adjustment needs to be made on the timer for the lobby. Once again I and several other paying customers have arrive before the stated closing time and find the lobby doors are locked. Perhaps you could institute a policy or procedure with a checklist which requires a change be made when appropriate. Your assistance is appreciated.

Why doesn't anyone answer the phone at the Rialto post office? I tried several times today and nothing. Very frustrating and annoying. Anyone else have this same problem? Who can we report this problem to?

Unhappy. We just moved to the city and they are not delivering our mail. They did for two weeks then suddenly stopped because our mailbox was not in the proper place. We were never informed. Then when they did inform us, one person gave us a deadline, the next two days we still weren’t getting mail, we called and they said they would give us time, then we got a notice to do it ASAP. Nobody knows what their doing, lack of communication and understanding of protocol, and we simply are being told different things and meanwhile we haven’t received our mail in the last few days. Way to be welcomed to the neighborhood. Extremely disappointed and frustrated.

Our neighbor does not have a mail box, it got damaged. We are getting their mail into our mailbox and not our own. Per informed delivery usps, we were supposed to get a letter from the IRS and dont have it ?!? I keep calling Rialto post office with no answer.

Our mail keeps getting returned to sender. This includes tax forms like our W2s sent back to our employers and invoices sent back to service providers. Birthday cards are sent back as well. Not sure what is happening, but it is labeled with "not deliverable as addressed" even though the address is correct.. what is going on???

I just moved to Rialto 2 months ago and haven't received any mail after 2 months after repeatedly contacting the office and asking for this to be corrected. I know the mail lady knows who i am by now by the constant inquires but still is sending my mail back or forwarding it, i'm still not sure which yet as i've been told 2 different things each time i contact them. It's so frustrating as all mail has been mailed to my old house i'm in the process of selling, 300 miles from me, or it's been sent back to the sender. Wow, i wish i had some other way of receiving mail besides the post office. After this experience i'm gonna be doing everything i can online bill pay. Hopefully this grumpy, over worked mail carrier will retire soon, cause her i don't care attitude is not okay with my mail or anyone elses.

Our cluster mailbox on W. Via Bello Drive has been vandalized repeatedly. Today, April 20th, 2017 the entire backside metal cover appears to have been forced open with a crow bar type tool as all the resident mail slots are completely open and exposed. This is a liability and concern for privacy and theft of our mail delivery as the entire cluster box is badly damaged. Please investigate and repair our mailboxes. Thank you.

Where is my vacation Hold Mail?? I have called the 909-875-4064 and no one ever answers. I have called 800-275-8777 and have a case number for my issue. The last 3 or 4 times I have used Hold Mail I do not get it delivered until I speak to my mailman. I finally used Hold Mail for ME to pick up . . . and it was delivered! Why is this a problem?? People go on vacation and use this program so their mail doesn't fill up our tiny boxes. I just saw an alternate ph# of 909-820-0363 on a previous review and called ~ ~ lo, and behold it was immediately answered and the postal worker said he found my mail and will deliver it to me within the hour! Now that is "service"; but, a wee bit late. .

Rialto post office has lost multiple packages of mine. This is unacceptable, the careless delivery and misplacing package is ridiculous. I've received packages from my neighbors all the time. We need someone to please investigate why so many packages are delivering to the wrong destination. Zip code 92377 please help.

Actually, all items must be properly classified for the employee to locate said items. That is, a parcel must be classified or submitted by he receiver as a parcel, not a registered letter. Without accurately detailed information, successfully locating said item is significantly reduced. I am sorry but, these are the facts.
