Theft by Invoice is what Direct-TV did to me. They added services to my bill that I never asked for and then sent me an invoice for the additional services.
I called in and demanded they remove the Add Ons they thought I needed/wanted which they did remove from my bill but only the "package price" not the extra tax it added to my bill.
So I sent them my "usual" monthly amount - now just waiting to see if they try to collect the taxes on the amount they never should have added to my bill in the first place. I would not recommend their service for 3 reasons - they add things to your bill w/o you requesting them,customer service people are not capable of handling issues and every-time someone sneezes in the neighborhood our service clonks out.
