Ticket escalation

I have opened a ticket about a missing device credit and some other complications from a line being deactivated by a store employee.  Also requested another ticket (fraud) be opened due to the same store employee adding additional tablet lines to my account that do not exist.

I have spent almost 6 hours on the phone with various departments over the last few days and have no resolution, my initial ticket has been closed with no resolution and my 2nd ticket was never opened.

I need an escalation path to find a real solution to this issue instead of being pawned off on every other tech support employee that openly tells me they can't fix any of the issues.
