Bad service @ walkin centre

I took both of my Explora de-coders and remotes in to the walk in Centre because we were not getting extra view in the rest of the house, after the technician had tested both de coders and the remotes he told me that if there was still no extra view then l must call in an outside company to check the wiring in the house.This l did at a cost of R1,002,06, and there was no problem with the wiring in the house, but there was a problem with the Explora decoder as the Multichoice technician had changed the signal output so the other TVs in the house had to be programmed into that new signal, plus one of the remotes was not working correctly.<br> I have visited the center three times and was assured that l would be getting a follow up call from one of the line managers (Molefe Moteme) after 10 days l am still waiting for this, l have on three occasion phoned his office number that he gave me, which was never answered but l did leave a message on his answering machine and still no call.<br> in fact l sent him and e-mail on the 14th on May which he has received to reminded him that l have not been contacted yet, this also he has not rep**** to.
