Dstv Multichoice *****ing from. Customers

My experience is horrible : I have two decoders currently active and I am debited full amounts every month. Now I want to connect a third recorder I was advised to pay R360. 13 to activate the third decoder. I paid to the account provided. After paying I'm now told third decorder cannot be connected because the money I paid went to settle outstanding payment. Look at this way How do I have outstanding when Multichoice has just debited my account. ******* by deceit. Serious consideration Netflix and forget all the day light *******. I paid for connecting third decoder and if they can't why refuse refunding me
