disappointed customer, decoder not working... :-(

Muzi helped me activate my 5S decoder but unfortunately after getting the decoder to update, it has not worked properly - no picture. Muzi did his part of getting the decoder to work but another issue came up-error E143 appeared and I had to call multichoice once again. I spoke to another agent whose name I do not recall unfortunately but the matter is that he sounded impatient and did not help at all. He told me he will pass on the issue to technical department to call me back. I asked the agent when I should expect the call, he said after about 1hr which I feel was very unhelpful compared to Muzi who went above and beyond to get my decoder activated. How I wish all/most agents were knowledgeable, patient and persistent as Muzi Botha. I am a vey disappointed customer. I will wait for the call.... :-(
