BIlling problem

Hi,<br> <br> DSTV sold me a new contract for the Explorar, assuming that I am taking the new explorar they did not ask to cancel my other subscription, they just kept on deducting premiums. When I asked last month why so money was again taken from my account they said it's for both decoders and I had to cancel it they don't do it automatically. Which I have done so beginning September and my account was in advance. This month they have taken again 2 premiums from my account, reason problem on their side. I asked about last months credit they don't know nothing about it and have only cancel my other subscription from this month. I have asked for them to go and listen to the recoding of last month and I am now waiting 2 weeks for feedback. Their service is poor and they will take a double debit order from your account without your authorisation and I feel that this is very *********. Are they now each month going to take 2 premiums and just say sorry they can't see that my other subscription was supposed to be cancelled.
