Auto and General want to bill me more because they assume i do not have a tracking device, when proof was sent to them

You have a call back feature, does it actually work? I been sending u call me requests, which sayd successful, but after numerous attemps, u have not called. The reason is, i did upload a netstar fitment certificate through the AG app, when i joined AG, which is last monty, but today u send me a sms stating since i did not provide proof of a fitted tracking device, and because of this u will bill me more. Are u guys for real??? Please go check, because i uploaded that document again to u guys, u are not allowed to just bill me extra because u assume i do not have a tracking device installed.

Irrate Customer still waiting for the call back to clear up the issue.
