Constant Xtraview problems with 2 decoders

I seem to be having constant problems with my Xtraview setup and keep getting technicians out who refer the problem back to Multichoice. I never had so many issues when I had my SD PVR, but now that I have the Xplora and HD decoder linked on my Xtraview account, nothing works the way it used to and it's supposed to be an upgrade. The final straw was when I app**** for my bouquet to be upgraded to premium this weekend. It seems that when the upgrade was done, my Xtraview was cancelled since it just stopped working again. When I called the call centre, I was told that Multichoice is in the process of a system upgrade and they will only be able to help me later on this week. In the meantime I need to be content with one environment instead of the two which I am paying for. This is unacceptable. I need someone to tell me how I can fix the problem with my Xtraview permanently because I am tired of calling the call centre for hours at a time without resolution.
