Awesome Customer Service!!! I had an oversized package delivered so the key was left in my mailbox. When I tried the key, it would not open. I called the post office and spoke to Glen, who said he would try and contact the carrier and get it to me. It wasn't 5 minutes when he called back and said he contacted the carrier and he would retrieve the package and bring it to my door. Within an hours time, the carrier was ringing my door, package in hand. Thank you so much to my Awesome carrier(sorry I didn't get his name) and Glen! That is Customer Service!!!

We order medicine for our dog online. It doesn't fit in our regular mailbox so the mail girl puts it in the large package box and leaves the key in our mailbox. The only problem is the key does not work. I left her a note in our mailbox and she did nothing about it...just left the key that doesn't work in the box and put new mail on top of it. Our dogs medicine has been sitting in the box for two days now and I have no way of getting to it. And this is the third time we have been given a key that doesn't work. Nobody cares if you can get to your mail or not. Something needs to change.

I was just sitting in my front room when I saw our mail carrier drive up. She got out carrying a long box so I got up to meet her at the door. Before I could open the door and threw the box on my porch resulting in it hitting my door. I opened the door and she was already in her truck. When I stepped outside she was pulling away. This is not the first time I have had problems with our mail carriers. I have been to the post office in person countless amount of times to complain about opened cards and packages, wrong mail in our box and our mail going to our neighbors. I am beyond frustrated at this point. I am severely frustrated and down right angry. There is no reason for this and certainly no reason for a box learly marked FRAGILE HANDLE WITH CARE on it to be thrown on my porch from my drive way when all she had to do was take a few more steps and go up two stairs. With that being said, something needs to be done. Action is required and this mail carrier should suffer the consequences. I really don't care if she loses her job. She clearly doesn't want to do it well anyway. Annoyed in Castle Rock, Vince and Lori

I had a package that was suppose to deliver June 22nd...it never showed up, and the tracking information says delivery status not available. I went into the post office twice. The first time I gave them the tracking number, they said they would get in contact with the carrier and call me later that day....this never happend. I called the very next day and still no one got back to me. So the following Monday I went in, and they asked for the tracking number again and said someone would call me, again this never happened. Today I call and AGAIN they say they will talk to the carrier when they get in and call me. I am betting I will not get a phone call. If you lose someone's package as a supervisor it is YOUR responsibility to find that package. Not tell me it looks like it is in castle rock you just don't know where. Put a little pep in your step and start doing your job as a supervisor AL and Chris.

Wow... I've lived in a good amount of places in my lifetime & NEVER have I had this bad of an experience(s) with a post office. My biggest & most annoyed complaint is that this PO is CONSTANTLY marking packages as delivered and it's not true, there's no package, there's not even any freaking mail! They don't even come, yet they say all my tracked packages are delivered. It's so annoying, I can't even explain. I receive a lot of packages, but they are NEVER delivered when they are supposed to be. I've had NUMEROUS packages and mail delivered to me that are for other addresses, I end up having to deliver them personally to the correct recipient. I should get a job there, at least I know I'd do my job correctly & not lie about when a package is delivered. It's incredibly frustrating that this PO is so horrible to deal with. It's sad, really.

I don't think the line is really busy; they seem to avoid any and all contact. More like the 1880's.
