DSTV - ageism, inefficiency, inability to communicate with clients and colleagues - no wonder they are bleeding customers

I have been a customer of DSTV for over 20 years. I received an offer - DSTV plus fibre, at a good price. I was just moving house, so app****. And there the joke started. They took forever to respod, then said there is no fibre. That was *******. Then they declined me - no reason at all. Then they corrected themselves, then failed again. Then they sent a technician for a new service and no fibre, so I sent him away. They apologised again, and escalated again. Finally they said that my credit check failed (I have a clearscore rating of 686. RSA average is 561, my area, Sandton, is 628. I have no bad debts, no arrears, no judgments. Someone let slip that because this is a 'New Contract', my age (73) counts against me. Inefficiency, pathetic communication and response, ageism, total failure in customer services. Could they have got anything else wrong? Over 20 emails and I still have no resolution.
