U. S. Postal Service--Tampa / Failure of Service

I have not received mail for five days at my address. The delivery supervisor at the local branch was rude and uncooperative and said it must have been my fault or the fault of those doing nthe mailing. There is no accountability at the post office (Palm Springs Boulevard and Bruce B. Downs Rd.) I have not receive3d a check, a bill, a letter, and medicine that have been known to have been mailed. Iwas not offered a complaint form so there is no record that anything is amiss. I have heard from others in the neighhborhood about poor service and poor responses to complaints.
