Just a week ago, my husband went into the post office to mail an 7x 4 envelope out. It had checks and gift cards inside plus the gift cards. First it rang up $2.+change, then she said wait this isn't bendable, so she got out a slot to make sure it would fit through slot door, though clearly, the envelope had an apt# on it, really, come on lady! Well long store short, it ended up costing $5.00! I guess she is the Queen of pricing our mail items! Wish the man that ran counter was there, he must have retired! So where did they find her? She must be on someone's black list!


The last 2 months I’ve had to goto the Post Office and pick up a package I’ve had on auto fill the the last 2 years. No one can tell me why it’s no longer being delivered to my house, only they don’t know what the problem is either and there’s no reason for me to have to pick up at the post office. Not sure what’s changed in the last 2 months but it’s starting to get annoying.


Saturday Nov 2nd I needed to mail out a small package, unfortunately and not surprisingly the lobby was open but, the actual counter was closed early, apparently the post master/employees can close anytime they want to. Even though I looked at the hours on the door and the website.. I was informed that she was closed for the day and she had better things to do. I pointed out the times on the door and website and I was within the time She became more rude and told me that SHE WAS DONE! I could come back on Monday, which I had to go to St Peters Mo , to mail out my large envelope package... For me to have to drive 23 more miles to mail out something or drive to Troy Mo..instead of the 6miles. . This is not the 1st incident on this post office being in total disregard to the posted hours of operations. Just the sheer Rudeness is appalling ..needles to say, considering the Rudeness and disregard for the posted hours.. I will not be using this post office Very unhappy with the treatment from my local post office and employees


For the last five days the Winfield Post Office has refused to deliver my daughter’s mail. I wish I could show you the picture I have of the area 5 feet to either side of the mailbox completely clear from snow and ice. My daughter is a single parent with two daughters who is recently unemployed. According to the US Postal Service, my daughter Has a notification from the state of Missouri on her food stamps application yet to be delivered. There is however a ten foot ice and snow drift covering the curb. My wife and I tried to break up the drift with shovels for twenty minutes in the frigid cold. We gave up. It would have taken over two hours to try to break this drift. It is going to be frigidly cold for the next few days. What does this mean? My daughter isn’t going to get mail for the next few days. This means every time there is cold weather with any kind of winter storm attached—my daughter isn’t getting her mail because the Winfield Postal service makes excuses to not deliver the mail.
