Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Billing disputes Florida

Barclaycard --Made a purchase with deferred interest 2 years ago. Made other purchase on the card also. Always paid above the minimum payment due. Barclaycard chose to apply any amount they want toward the deferred interest or non at all, Now 2 years later having paid them over $5000.00 on the card they added $730.00 in interest because of all the above minimum I paid only $300.00 went toward the deferred interest. There statement does no specify how the payment above the minimum payment is allocated. I believe the amount of interest accumulating and the amount of my payment going toward the deferred purchase should be clearly stated on the statement. I believe this disceptive practice rises to the level of consumer fraud.
