By far the worst customer service i have ever dealt with. got hung up on because i asked a question they didn't like. mail stopped being delivered for a week so i went in to see why. got told it was a delay in the change of address. which makes no sense because i was getting mail before. got tolds only one of the three people i changed the address on when through which makes no sense because the were receiving mail too before it stopped and they charged me for it and i have the confirmation of address changes in my email. so the worst part was that i had a letter addressed to me at my new location and it never got delivered but the Post Master said that because the other peoples names were not addressed and the names were not in the mail box they wouldn't deliver it. so heaven forbid you have something addressed correctly they will still not deliver it and give you a complete attitude saying that i know nothing about policies and then hang up on me because i asked why it wasnt delivered if it was addressed properly and named to the one person whos change of address actually went through? i will be contacting whoever i need to above the post master to fix this. but honestly horrible horrible service. i was not yelling. i was not cursing and you hang up on me! wow.


Please let India how much I appreciated her. She went above and beyond her duties. She is wonderful.


I have not had any of the personnel take an "attitude" with me even when I was having an issue getting an item delivered That problem was an address change filed electronically never made it to the local post office or carrier I have found that in customer service situations, If you approach in a calm manner (you can be exacerbated/frustrated/confused but calm) it helps. and yes sometimes weird stuff & Human error happens. Postal workers are people too


Do not ship abroad from this post office- maybe try Mystic or UPS! Shipped a gift to my boyfriend in the navy in the UK and for some reason the package was sent back to my house after landing in the UK post office. Both sides ( the Royal Mail and USPS) do not know why it was shipped back to my house- both saying “this has never happened before.” Instead of USPS being helpful and accommodating over this, when I was extremely upset the $40 package I shipped failed to make it to its destination for no reason at all, they refused to refund my money or help to expedite the package back to the UK. The Post Master, Steve I believe, and supervisor, Megan, failed to provide me any support simply saying it wasn’t there problem. After I called the USPS customer service line twice explaining to them my situation they said I would have NO PROBLEM getting a refund on my package. I explained this to the USPS Groton location and still they refused to refund me- major discrepancy between the local branches and main USPS! DO NOT SHIP INTERNATIONALLY THROUGH THIS GROTON LOCATION THEY ARE NOT SYMPATHETIC AND WILL NOT GO OUT OF THERE WAY TO PLEASE A CUSTOMER! Horrific customer service!


Woman who answers the phone is more than rude and if she doesn't like her job I know plenty of people who would love and be happy to reliever her of it I'm looking for someone higher up to contact


I totally agree. I had the same problem with her. A real nasty person.

priority mail huh? pssssh you are NOT priority here


I try to avoid having to contact them by phone. The woman who answers the phone was very rude to me both times I had to deal with them. She was very unprofessional and unhelpful.


She should lose her job. I've had a few calls with her and she's a very nasty, rude person. She should learn some manners. Her name is Jessica.
