Santander Bank Stealing Car payments Fort Worth Texas

 I financed a car through this bank in 2015 and never paid a late payment. My car was reposed in June 2016 and realized this bank was never posting my payments to my account. I then contacted the president department by via email and he ensured me this problem would be fixed but the problem is still ongoing to today. I was asked to fax bank transactions, which I did, with no results. This bank deducted the payments every month from my bank account and never posted the payments to my car account. Now when I call no one responds and my calls are being routed to a voicemail machine. I need help this bank has being stealing my car payments since 2015 and reporting false information to the creditors. I have documents proofing this bank is a scam and they are stealing car payments.
