DSTV internet

They have debited my account from March till now for their Internet service which I never received & I don't even have the router.I have send an e-mail at *** but still no 1 had the decency to contact me..What makes me even more irate is that they have listed my name at the credit bureau as though I owe them while in actual fact they owe me.Each time I call they promise to get back to me & that the matter has been escalated but it still has not & yet my bank account is still debited every month for the service I never received.. Multichoice DSTV has the worst customer service I have ever ever seen
