DSTV BAD SERVICE and NO Feedback on issues logged

For 4 months I have being tying to contact DSTV Multichoice to resolve issues with my online profile. I did a change of Ownership from my late husbands name to my name and since Oct 2019 the decoders linked to my profile is incorrect, I cannot see my billing information and we also cannot use DSTV NOW or Showmax. I have logged at least 7 incidents/tickets and each time I am told that they are escalating the issue and will get back to me. No one ever gets back to me. On Tuesday I phoned the call- center again and spoke to a friendly lady called Confidence. After being on the phone for more than an hour, she promised she will phone back at 15h00. 3 days later, still no reply. I am now really fed up and cannot afford to spend hours on the phone or on live chat. I am really disappointed in the service I received from the DSTV agents
