Review E48 - E32

I have been experiencing Error message, accompanied by total black out, loss of signal, freezing pictures for the past 6 months. The problem often starts arround 9 pm until mid night. I have engaged a multichoice accredited technician. I called him many many times to inform him that the problem was not fixed. He never bothered to come back or assist me on what to do. I have called multichoice many many times. No help. the error does not appear on fix errors. Virtually everything on the internet applies to South Africa. There is very limited information on Multichoice Botswana. I am paying to paying to watch the worst TV. I am absolutely annoyed. Can anyone assist please !!
