We were offered 0 % interest convenience checks from Barclays Bank, and used XXXX of them before the expiration. On our next bill we were charged interest on this check, we contacted the bank at least XXXX times by phone and e-mail, sent them all of the requested back up and have not had this matter resolved. At this point we are being charged over {$100.00} interest for this 0 % convenience check, we need relief from this bank.
