insurance registered without consent

I am so upset right now with DSTV and the sales people that constantly register insurance policies on the DSTV account and that has resulted in the account being in arrears with R518. Last month I was not aware that the insurance had been registered I had to pay an additional amount. Today I was sent from pillar to post just to get a cancellation and a reversal. The first agent sent me back to Multichoice and the agent at Multichoice sent me back to the insurer. I now need to wait for 48 hours to be re-imbursed and am now inconvenienced because of this. I cant go pay an additional R500 for insurances i never registered for.
