FAULTY AND TEMPING OF CONNECTIONS BY DSTV INSTALLER

I recently ( few years back)changed my packages and decorders to explora ones and we never had issues till last week. The Xtra view decorder started showing the E48-32 error and as time goes by the E143 error, we tried all methods we could to solve the problem with your consultants and they said the issue might be the hardware is *******ed we must take it to the nearest branch for further assistance, I did so and they cleared and cleaned the decorder and when I arrived at home it still gave me the same notifications , I went back to the branch with both the decorders so they can figure out what's wrong and they fixed everything and when I got home same issue started, we called a dstv Installer and they did their diagnose and said that the previous installer messed with the cables thus when they updated the systems of their side for the Xtra view it is now giving us issues. This is very unprofessional, why why sending us installers who mess up with installations rather than doing their job this is really really disappointing and I can safely say that I don't want to use your services anymore - now I need to pay for ANOTHER INSTALLER buy a new cable for YOUR FAULT AND YOUR INSTALLER, worse part - you didn't even keep record of that installer you sent us This is very very unprofessional and disappointing. We will be canceling out services with you- clearly you don't care about your customers.
