Continental Finance Company, LLC Credit Card Complaint

Continental Finance Company, LLC Credit card department,

Delinquent account California

Continental Finance Company took advantage of me by taking DOUBLE Monthly Minimum Payments from me for months and only allowed double payment ( on-line payment and by phone when I checked to see if minimum for each month was being received by CFC. We I found out by looking at - 2015 Monthly Statement CFC was actually receiving $70.00 and not the agreed upon $35.00 I contacted CFC to ask and was told to turn off auto pay and I would not suffer late fee or other penalty while the matter was being fixed and that I would be refunded for -/-/- double Minimum Payment received by CFC. I was told I could use the Refund for - 2015 payment. I have not received a Refund and CFC still charged me with a late Fee. I have never been late with a payment. My account with CFC is now Delinquent. I contacted my bank - for help to stop double payments going to CFC. I think I was being double charged Interest for each double Minimum Payment I made. - Contacted CFC. That same day or the next my account was charged late fee and is now somehow delinquent. How can my account be delinquent when I never missed a Minimum Monthly payment? On one or two occasions CFC applied the Doubled Minimum Payment for the next months payment, like - - and other well known Creditors do.
