Poor service

I called multichoice customer service and the advice me to go to the nearest branch to do a change of ownership what I did on the 6th September, at home we were using my younger brother decoder and that decoder doesn't have that port of hdm1 cable and I was having the decoder that is under my name that have that port so I decided to do a change of ownership to my younger brother till today the decoder is not active. I need the one that was mine the hd1 to my younger brother so that we can use it than to buy a new decoder while the is other decoder is just used.
