Fashion Bug false credit card claim , Internet

I need to update my complaint.  I just got off the telephone with Fashion Bug's credit card group and they confirmed I did not have a credit card with them nor did I owe them $600.  I then contacted the collection agency, Portfolio Recovery Associations.  When I explained what I learned and gave them my last four digits of my SSN, they checked their records and confirmed I was correct. They had found my name and number in the phone book.  My name was SIMILAR to the one in their files so they called me to collect teh Fashion Bug funds.  They were calling the wrong person!  In the initial call, the call was monitored by a manager who stepped in to get my payment from me when I was aggressively arguing that I did not have a Fashion Bug credit card. She threatened that since it was on my credit report, I could only remove this with full payment. I was so floored, I agreed to pay it, knowing I could not argue with them.  I figured I could research it after the call and figure out what to do. After my call to Fashion Bug, I called them back. This rep verified my SSN.  She put me on hold and then came back to confirm I was not the person they wanted to talk to and who owed the bill.  Thank goodness!  My complaint should be against Portfolio Recovery Associates.  They called to threaten me for payment and I was not even the person they wanted to call.  I was so floored at first, I could not figure out how I could prove to them I did not owe Fashion Bug any  money.  Lesson learned -- give them my last four digits of my SSN to ensure I am the person they have on file.  I have to admit, I never thought that I was not the person in question. I was so focused on figuring out if I had created such an account in my youth and somehow forgot about it.
