Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Billing statement California

Hi, I have a credit card account with barclaycard called - - card. I have my payment setup on repeat pay for the " statement balance ''. My last balance was $670.00, which I paid myself on - -. However, barclaycard deducted another $420.00 from my checking account on - -. When I called and complained about the situation, they told me that the repeat pay will deduct " current balance '' up to your statement balance from your account even if you have paid the balance in full. This means they can deduct up to twice the " statement balance '' in - billing cycle. Although the manager told me it is in terms and conditions, I was not able to find it. This situation created problem for me since I need to find money to pay my other bills. Also, I think it is a way of taking benefit from customers and deducting more money than it should. I feel that I am not the only - abused, and other customers could have the same problem.
