Mrs Mokoena

I have a contract with DSTV for 24 months where I am paying R936 and all of a saddened my contract went up to R1280, when I question that I'm being told that I cancelled the contract, does this make sense leaving a better payment going to pay the high price. I've been calling DSTV to no avail of them in helping me. I asked them to listen to their recording an come back to me nothing has happened and I ended up down grading thinking that things will be better but still the amount is sitting on R1100 no one has an explanation for me. I would like you to help me on this matter since DSTVis reaping me off.
