Pathetic service

Recently had a problem with my dstv decoder where it was not picking up a signal so I contacted these guys after seeing their details on the internet. Their service is pathetic and it is as though they are doing you a favor. They overcharge and tell you that the technician miscalculated the cost. I would definitely NOT recommend them to anyone. The second time that they came out and charged us again , they didn't even resolve the problem, They didn't even produce a receipt. On their website that advertise that they give pensioners a discount but they still overcharge.
