PayPal Credit Bill Me Later, PayPal PayPal charged finance charges of $1991 for missing the payment by 3 days Timonium MD

I had a $16679 balance with No Interest and No Payment plan with PayPal that expired on 11th March. I was under the impression that I will have a billing cycle before I can payoff the balance. I had funds to clear off the balance. But PayPal charged me with $1991.05 in interest charges on 14th March. I checked my account on 16th and realized this and immediately contacted PayPal customer service and paid off the balance and request a refund of finance charges in lieu of my mistake. Customer service supervisor mentioned that they couldn't do anything about it and asked me to send a letter to their head office in Timonium. I sent a letter (faxed and mailed) to which I just got a response saying the request has been completed. Nothing happened for 48hrs and I called back the customer service. They mentioned that the request was denied. No courtesy at all. Out of rage I asked them to close my account. I even mentioned to them that I was out of country visiting India from March 4th - March 12th, I have proof for this, not that this is an excuse, but still something to consider if they can.

I think, it is ridiculous practice to charge that much interest for a simple mistake and completely shut me off. Is there any law that could help me. $2000 is a lot of money. Any help with this issue is greatly appreciated.

Thanks! Pradeep
