We have had no mail delivery or pickup since Christmas. Please explain.


Only I could look up the nearest POST OFFICE, drive there, wait in (a short) line then be told WE DONT SELL STAMPS HERE!


My mail delivery has become very sloppy in the past months. I frequently get other people's junk mail but, now, I am not getting important things. Yesterday, my Social Security Benefit Statement was delivered to a neighbor (along with her own). I feel fortunate it was delivered to her and not someone unknown since the statement has my social security number on it! Also, I have not gotten a bill I've been expecting and now it's due in a couple of days. I'll have to call the company and put the payment on my credit card. Not something I care to do repeatedly. Please suggest your delivery people be more careful and, maybe, not talk on the phone.


I need the prices of a p.o. box
