R1989 DSTV Premium in one month

I previously owned an HD PVR decoder and my monthly premium was R737. I then upgraded to the DSTV Explora decoder at R799 per month on 15 January.<br> <br> My account was debited at the end of January with R1989. I called the call centre to request a refund as the debit order was R1190 too much.<br> <br> The consultant I spoke to was very rude and said that I should have requested that they cancel the previous decoder when I signed up for the Explora. I informed her that I had in fact asked the consultant if I would be charged double and he had laughed and said no definitely not. She said they would need to listen back to the recording to check if this was true. <br> <br> What if I hadn't asked the consultant if I would be charged double, then I wouldn't be able to get a refund??!!! Why didn't the consultant ask me whether I would like to cancel the other decoder??? Who in their right mind would pay two premiums, when there is no extra charge for extra view?<br> <br> Also she said that I have been charged pro rata for the Explora for the month of January seeing as I got it on the 15th. Shouldn't I then be refunded pro rata for the HD PVR decoder seeing as I paid in advance for the month of January at end Dec?
