Chase Bank JP Morgan Chase Bank lost my car payment Indianapolis Indiana

Friday Sept. 11, 2015 - I went to pay $300 towards my car loan.  I placed 15 twenty dollar bills (a total of $300) in the tube with my picture id, sent it through the vacuum at the drive-up teller window.  I waited for about 10 minutes then the teller asked what I wanted to do with the $20.  I corrected the teller a said there was $300 in the tube.  She laughed at me and said if I have a problem to come inside.  I said I have a huge problem you just like lost my money.  I went inside and reported the incident.  The Vice President rolled her eyes at me and didn't even offer to take me back to her office.  I offered to stay until the mess was resolved.  I was told cameras were off site and requests for views had to be approved through corporate.  I was told to leave and wait for a phone call.  The footage was reviewed and the bank can't find my missing $280.  I have left messages and sent numerous emails. I still haven't had a resolution to this matter.
