Im having issues with my mail, help?

[Alex]

I like to do a bit of online shopping but for some reason my products are being sent in and then returned to the sender, the first question to ask is "is your address correct?" It is though I've checked even my apartment is on there. I've been doing it for a few years now and this problem has just now appeared. I'm not sure how to fix the problem. I used several different shipping companies.
I realize that this is a weird place for this question. But I honestly couldn't find an appropriate category for it and this was the next closest thing having its relationship to the Internet.

You have to ask each of the shipping companies you're having a problem with, what their problem is with your address. They are the ones who said your package was undeliverable and returned it to the sender.
