Since I moved to Oakville, I get my bills periodically. I complained to the Post Office who said "we deliver all mail sent to us". I get my Discover bill every other month, my bank statement periodically and my car was almost reposed because they didn't receive the previous 2 checks I mailed from my home.Since I started mailing my bills outside of Watertown I have had no problems. I still do not get my credit card bills regularly but I am not going to fight with the Post Office when I know they are the problem
