Unacceptable service.

This is the worst customer serves I've ever experienced. I was offered the new explorer ultra on a 2 year contract. Since I've started with it 20 days ago, it's been issues since the start. I'm already on my 4th new decoder. I'm on the phone with them daily about issues. Again today I get errors on anything I want to watch. Apparently my PVR functions is disabled. I phoned, but yet AGAIN I have to wait 24 to 48 hrs to be fixed. They can see what's wrong, but will take 24 to 48hrs to fix (apparently they not allowed to fix it) REALLY....For every fault to date, they claim 24hrs, eventhough 24hrs has passed. If you ask for management, its always "the manager will phone back in 15mins", but till now, no manager has phoned me after I requested it numerous times. This is absolutely descustng and unacceptable. I've laid complaints everywhere, but just seems nobody cares.
