Terrible service by Multichoice

For the past week the Xtraview was removed without my knowledge, In trying to solve the problem, I spent many hours at the walk in centre and on the telephone. I was told to have patience as a system upgrade was done and they are experiencing problems. The first outcome was that now my primary decoder was also not working correctly. Up to now my problems have not been solved and only promises have been made to call me back every time I visited or telephoned. Nobody has contacted me and my service for which I am paying is still not fully working and the original problem still not solved. Also no indication as to when I can expect at least a response or when it will be working. THIS IS REALLY HORRIBLE SERVICE
