JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Payoff process South Carolina

I would like some help/information. I have a credit card with Chase. My payment is due today. This morning I made a $200.00 payment. When I got home from work - - and I knew my paycheck had cleared, I went to make another payment to complete the amount owed. The online process would not allow me to make another payment, so I called. The representative would n't allow me to, so I asked to speak to a supervisor. -, the supervisor, also informed me I could not make another payment for 3 days from the same checking account. I asked where it stated that I could n't make a second payment. He could not find anything, but refused to take a - payment, which means I will be paying interest on the balance - $1100.00 -. What can I do? Thank you, - -
