DSTV

I have made various attemts to try and cancel my DSTV subscription, but to no avail. You can NOT cancel your subscription via What's App or on the Self Service site, even though they say you can. I have sent them an email via their webdite but received no response. Today I phoned their Customer Call Centre and was told I'm number 11 in the queue and my call will be answered in appropriately 16 minutes. After 26 minutes I was still waiting to be attended to and was eventually cut off. They are absolutely pathetic! All I want is to cancel my subscription and be rid of Multichoice FOREVER!
