Payment Reversal - No Refund to Account

I pay for my DSTV manually via credit card each month, have been doing so happily for a year now. On 25 Sep 2015 I paid my R779.00 and on 1 Oct 2015 @ +/- 4:44AM the payment was allocated to my account. Now, on 7 Oct 2015, the payment was reversed. I HAVE HAD NO REFUND! This is THEFT, as I have not requested ANY reversal or refund. Come 1 Nov you *****s are going to cut me off, and rest assured, should this happen, you can shove your \service""; it probably means f**k all; as I was told I would be contacted within 24 hours;that was 3 days ago."""
