Appalling service from DSTV

I have subscribed for Internet through DSTV. It was bad enough that they have decided to cancel the service, simply informing subscribers that the service is to be discontinued but, as soon as they did so, they no longer support the service through their call centres. When I phone the call centre I am told they no longer provide the service. When I insist that I have a contract that only expires in November, they finally give me an email to contact (techfibree****ultichoice.co.za). There is no way to contact them by phone. This is supposed to be Fibre ESCALATIONS. I have proof that my email was read yesterday but now, 16 hours later, despite several follow ups, nobody has contacted me! In desperation, I phoned the call centre again this morning and managed to persuade them to do something. They promised that spomebody would phone me. I'm still waiting. Clearly, DSTV/Multichoice, once they close a service, don't give a damn about existing customers who still have a contract.
