Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Identity theft / Fraud / Embezzlement Nevada

My Barclays credit card went missing, I explained this many times on the phone and sent many faxes they requested and in the end they now stick me with the bill. I did n't buy anything and I 've never heard of most of those places. I talked to some arrogant guy on the phone and he said they had me recorded saying it was n't fraudulent charges a tthat time, but that caller was n't me. Anyway I did n't make any charges on my Barclays Mastercard since - -, and I 'm billed something like $6000.00 I will of course never pay and I get bad credit because of the incompetence of Barclays.
