Complaint regarding Computer Book Direct Book Club

Hi,

I purchased some books from them around 3-4 yrs back I don't remember and I

think I paid the amount.

After that I moved to India and now I have come back in US after 3 yrs

staying in India and when I ran a credit check, they have put 57$ in my

collections.

I don't have any account number or any details how to handle this. Please

suggest something so that I can get it removed from my credit history.

Regards

-Shelly
