Poor service

Really poor service from the service agents. I'm having a Xtra Veiw error from my secondary decoder from Saturday day morning. I tried all the necessary basic fault finding & then decided to call the service center on Sunday afternoon. After having to wait on the. Phone for almost 10 minutes I received assistance from a service agent. She attempted to reset the decoder from her side but the problem continued. She the told me she will escalate the problem to the Xtra Veiw department. They were supposed to call me back. Today after I returned home from work I noticed the problem is still there. I called again. After the same process a service agent assisted me. This time after one attempt of resetting the system the problem was resolved. I mentioned to him that a few of my channels was distorted & he advised me to switch of the power to reset the decoder from my side & it should solve the problem. Well those channels was still distorted but it didn't bother me much, at least I had my Xtra View working again or so I thought. A hour later the same problem. I called again & again I had to wait a long time for some assistance. Finally after holding on for more the 10 minutes later, the same procedures was followed & me getting really annoyed. I was somehow disconnected & I expected the service agent to call me back but to my surprise nothing. Again I called back & again I had to hold on for a long time before someone answered. At this point I asked to speak to a supervisor. After having to confirm my credentials every time I alled this service agent asked me for my phone number. I could not believe what I was hearing. Anyway I gave my details & she assured me the will call me right back. It's been more then 2 hours now & still nothing from Multi choice. I have experience of a one day late payment to them & the immediately disconnected the service & I had to pay I penalty to reconnect. But with me the client having a problem they can't even make a simple phone call to me to try to help me. I'm so disgusted with this service. I think being such a long time client to multi choice I deserve better service. ????
