Complaint Review: Merchants' Credit Guide Co.

I received a letter from Merchants' Credit Guide Co., saying that I haven't paid bill of AT&T for $84.77 and went to them. And also, AT&T closed my credit card as well. Funny thing, I am still using the same credit card. It was never closed.

I called AT&T and they told me to ignore the issue and they can't send me the report which are more than 6 or 8 yrs before. First of all, my credit card is not closed, I am still using it. Second, if I haven't paid the bill, it should have shown up in the bill. This doesn't make any sense. I am getting bounced from both At&T and Merchants. I don't want to screw up my credit so I thought I would pay the bill even though it doesn't make any sense at all.

So I called their manager "Steve" and left message so many times to give me a call back. But he never respond. Please help what I should do? Their customer service people are very rude and very cheap people. Please let me know what I should do? Should I pay off the bill?
