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
