Suntrust Bank Lost payment and bank fees Internet

After many attempts of making my car payments online, sending checks in the mail,  month after month, Suntrust saying they never recieved it ontime and countless late fees, an employee of the Regency Branch in Jacksonville told me to use the night drop box. She told me that they would retrieve the check the next morning and process it on time. Great. I dropped my check as instructed into the box. I waited and watched my account , and moneys were taken out of my Regions Bank account. 10 days later I start getting phone calls saying that I need to make my payment. I told them I did and said they would investigate. The phone calls came to me at work constantly. I told them to stop the harrasment that I had made the payment. I went into the branch and they all but called me a liar stating that they didnt think I actually dropped it in and that I may have been mistaken. They asked me to give another check.  Since this had happened not once but twice before , I refused and told them to find the check. After about 6 weeks and constant calls to me, I gave them another check. 6 1/2 months later, with no announcement to me, they cashed the original check.  I went to the branch and the manager did not want to talk to me. There was no apology and when I asked for fees to be returned to me they told me that this was not a Suntrust Policy. I have been burned for many, many late fees, harrassed and I feel treated disrespectfully by this bank. Be warned, if you are borrowing money for a car or anything else, no matter what a deal it looks like at the time, run as fast as you can the other way from this bank. They are heartless theives that are screwing people over.
