Have not received my mail for 3 days. What happen to mail person. Tried calling only got recording the told to wait one hour for the next available representative. Not Good 😤


Why is it impossible to speak to a real person???


outside deposit mailboxes were blocked from use at Williamson Dr post office. why?


I called ur post office and could not get a real person on the phone this is very upsetting


Postmaster Skidmore, I would like to send a big thank you to one of your employees, may wong. Recently my medication from the V.A. Was lost in the mail, when I talked to May about them and took the info and started searching for them. this was on Friday the 24 of November, she called me on Friday night and on Saturday afternoon to tell me she did not find them, on Monday morning I got a call from May telling me my medication was in the post office, she went one step further by offering to put the meds at will call for me to pickup. Half of what May did was above and beyond what she need to do. So from one retired veteran i would like to send my deep thank you to May Want and you.
