Wells Fargo Financial National Bank Deceptive bank.. BEWARE Dallas Texas

I took out a Wells Fargo Health Advantage loan one year ago to pay for my laser surgery . It was offered to me by TLC center so I did no research on this bank. I was told I could make payments for 3 years interest free.. That was the first lie. A few weeks ago I got a letter saying that I needed to pay off the balance by July 13 to avoid the high interest payment. So I called the customer service line and made the payment through the automated services. A week later I asked my bank if any money had been withdrawn and was told no. So I called them again and spoke with a rep. I was told that the routing number was different and the automated system couldn't do that.. Ok. so we tried again.. this time all was fine. A week later I get a letter confirming I had authorized them to take the money out of my account.. Well nothing happened again. Today I get a bill for $1200 interest because no payment had been made!!!! I called again.. very upset of course and was told the payment had not been able to be processed. I should call my bank. So I called my bank and the manager said that the numbers were correct and that they should contact her and fax a confirmation explaining why they transfer could not be made.  I called back and after 20 min of waiting I was told that perhaps the amount had been too large to process... It was $2800! Since when is that too high??? But if I made a payment per money order or cashier's check they would be so kind and waive the interest fees.. 

I sent the money order away and called them to tell them to close my account..and I wanted this in writing... I was told again that might be difficult.. They had to speak with their supervisor... Now I supposedly will get it in writing. I will never deal with such a corrupt bank like this again!! I'd like to know how many innocent people they have ripped off...
