FAULTY SYSTEM - FRUSTRATED

I had DSTV installed in my new home in July 2015. Since then, I've been unable to sort our their inability to deduct money from my account. I call them each month to re-confirm the debit order details. Each time they confirm a pro-rata amount to be deducted, which then never happens. Today I called again, upon which Nikki Kekana (Team Supervisor) promised she'll send me a verification form to sign to get the account verified - (I've never had this problem with any other company debit order), and yet I still haven't received the letter - which means again another phone call at my expense and explaining everything from the top. I am desperate to get DSTV cancelled and my moneys spent refunded - I'd be thrilled to live without the monthly frustration of having to deal with their system - Unfortunately, that too cannot be done they say. By far the worst service ever encountered. I truly wish I could re-trace my steps - I never would have gotten DSTV
