Service not great and seems like no regular delivery person. Had mail to go out today and it was left here. Apparently carrier may have had no delivery for us but did not bother to notice my outgoing mail to be sent. Getting tired of this bad service.

I have called the main office in Sioux Falls for 6 days and left messages concerning my mail not being delivered at Dakota Post on Potsdam ave going on 6 weeks. You might have it on a PO box 2976 which is PMB 2976. I have meds being shipped and of course my mail. Not getting back to me will cause me to write to the Postmaster General and complain. My number is (208)6900813. Thank you Angelo Moreno

Had great service, fast and friendly! Very helpful and efficient today. Not sure if just a fluke or if they had a turnover but I really appreciate their help as I had just moved to SF and needed assistance filling out forms.

Horrible service. Could not reach with a phone call for 20 + times and contacted both numbers and fax. Also, paid $45 for a copy of a mail key, been over a week and no word yet, was told 3 days or less key would be finished. Absolutely would not recommend this post office.
