CHASE AUTO FINANCE Somehow they seem to loose my payment! Internet

I financed a car with Chase Auto Finance out of Indianapolis, Indiana in October 2009, all my payments were on time. The first problem I had with them was when I was 1 day late on my payment which is due on the 21st of every month. They called 3 or 4 times a day on the 22nd. If this isn't harrassment, I don't know what is. Then this month (July 2010) Mrs. Walker from Indy calls me and tells me that my April payment was never made. I made my payment May 3rd, yes it was late and paid the late fee. This phone call occurred on July 16th. Why didn't she tell me sooner? Well, then she called again 3 days later, I didn't answer so she called my fiance's mother, asking if she knew where I was. My payment for July is due on the 21st keep in mind. So, she called again on the 27th of July and when I talked to her telling her that I made my payment for April on the 3rd of May, she says, oh no you misunderstood me, I meant June. I'm not deaf, and I heard her right. Long story short, what happens is they can't find my May payment. I always go into the bank to make my payments, mind you I have NEVER not made a payment.

Now Mrs. Walker tells me since I have a payment missing, and that my July payment was due on the 21st, they are coming to take my car July 30th. I'm not even 2 months behind. I know I made my payment and since they can't find it, in their eyes I have to repay the lost payment. And on top of the lost payment, I am guilty of being 7 days late on my July payment. I was terminated from my job and explained that to her. She doesn't care, she told me that I am 2 months behind, and anyone can do the math, 7 days late is not considered a month which is 30 days. I hate this company with a passion! How can they come take my car for being 7 days late, and blaming me for a lost payment!!!

I will never deal with this company again!!! I have talked with many people about Chase Bank and they are rude, harassing, and seem to loose customers payments like crazy.
I just read a post where Chase Bank lost 2 months of their mortgage payments totaling $4k!!! And they have the cashed checks from Chase to prove it!!

Why doesn't someone do something? Doesn't the FDIC get involved in Bank fraud? It's not the consumer, it's the business!!!! If someone has answers please keep me posted.

Gratefully appreciated.
