Normally very great but I try all Saturday morning right after mailing letters which I believe I forgot to place stamps on so I was trying to get a hold of them so they could place them in my mailbox Needless to say they wouldn’t answer the phone Very disappointing


Disagree with Maureenz completely. Staff very friendly even when busy. Go out of their way to take care of me. Very happy with the service. Very busy but the best of all the offices I have had occasion to visit. Never had a problem in the 30 or so years I have used them and they are super good.


Terrible customer service there now! Ever since they’ve moved and have new staff. Abrupt with elderly customers, unfriendly and non smiling in general. It doesn’t cost money to be nice for goodness sake!
