XRE- 03059 & Missing Channels

Several service calls and still missing Channels like Lifetime, Nick, National Geographic, Fox News.  It has been several months.  3rd service call determined it wasn't in my house that the signal was interupted from street.  I have a new line from the street.  Alll my calls to customer support have told me a supervisor will call me back no call backs.  It all noted in the system.  No offer of refund for lack of service.  What should I do?
