Bunch of ******

Last month was in battle with dstv overcharging me on my service. Now I checked my statement for the month of November and again being overcharged. Use to pay less than R800 for compact plus, since the change of decoders and new 24 month price lock contract I'm being billed over R1000 which was never agreed with I was at the walkin centre. New month with same issue, I'm starting to think this is done deliberately. Taking money which does not belong to them. It took almost 3 weeks for the refund, so I have to go through the same process again.
