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. .


that's because that # is wrong... I was given the same# to Rialto from their 800# you can reach Rialto Post offce at 909-820-0363


I as well have the same problem of them misplacing my packages(that have tracking numbers) and mail and it's been going on for months already. All my information is correct its the postman's fault that keeps misplacing them
also no one answers from that number, it appears to be disconnected no matter how many times you call them


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.
