*****ulent Insurance Premiums Billed On Customers' Accounts

Dstv (Multichoice) has continuously billed some insurance waiver premiums on my account that I have never taken up or agreed to! To make it worst, when I asked to cancel they simply do so going and never return or back date the premiums they *****ulently billed onto my account for the past 8 months. They simply claimed knowing my next of kin and for that reason claim I must have spoken to them regarding the insurance! No proof whatsoever that I have taken the insurance!
