JPMorgan Chase & Co. Credit Card Complaint

JPMorgan Chase & Co. Credit card department,

Payoff process Florida

I contacted my credit card company to get on a plan to pay off some outstanding debt on a closed card. We agreed on a $15.00 min monthly payment down from $25.00, but interest is still being charged, meaning that I can only pay less than $10.00 a month altogether. Is their anything I can do to stop the interest from piling up?
