USA Magazine Exchange Magazine ripoff They got me. What happens now? Glendale Arizona

Everything was fine and dandy. I recieved a phone call around march of 2002 for a deal i thought was wonderful. I have called a few times and exchanged magazines for the orignal ones. No problems at all.
Well now where am I? Sounds like I am not alone.
I have not received 3 of the magazines now for 2 months. The other two run out shortly. I have been trying to call and it has been busy. Today when I tried to call the operator has told me that my area code has been blocked from calling the usa magazine exchanges number. Now I am mad. Everything been kosher while they recieve my money. I am paid in full and wont get the rest of the magazines I have paid for.
What do I do?
