I take it wirelessdog works for airnet? LOLThe amusing thing is that air net.llc created the billing mess and now they want to paint you as the cause of the problems.The only thing I would have done differently is I would have paid any invoice that was sent. This way they would be completely on the hook for the issues.It sounds to me that you need to speak with the AG of Texas.
Regardless of them creating the billing mess, at least you realize that the bills should have been paid. There is the different between a responsible adult and a deadbeat like the OP.
