Auto loans are harder than the regular credit card late... but it was definitely worth your time to call. Sorry you didn't get far, but glad you at least made it to a supervisor.
They can correct it, stinks that they would not but that's not the end. You might want to write a GW letter explaining that this was not your fault and would they kindly correct this issue... but send it to someone higher up.
Or, yes you can file the dispute now and see if that clears all up.
