Not Requested - But being Charged - *******!!!!!!

I received a Explora decoder in December 18 2015 even though I did not request one. DPP department pass the buck all the time, have spoken to seems like 100's of staff members as well as Team Leaders, everybody promises to sort out their error and still nothing. Got charged R350.00 more than normal in January, refund is still waiting according to them being escalated, now as problem is still not fixed, due to pay R849.00 extra again. As a client you can not speak to a Supervisor as advised by the call Centre staff, unless they first escalate a query . Phoning them 2-3 times per week since December, NOT ONE SINGLE STAFF MEMBER IS CAPABLE OF DOING ANYTHING. WHAT IS GOING ON? Is multichoice /DSTV looking to loose customers. What you have done is *******, if a service has not been requested, how do you continue to charge people and not fix your mistakes. Empty promises seems to be your Company Mission. Extremely annoyed and very disappointed after so many years of being a loyal customer
