Disgusting service with accounts

Hi have a Price Lock contact with DSTV I played the Happiness Wheel and won the year subscription and an upgrade for 1 month. The year subscription I called in as it won and then bombed out giving an error. I sent an messages in Dstv messagener and I advised that I see they have updated my 1 year free subscription now I look on my account and last month's subscription was reversed, I paid it now, but your service regarding billing and your call center is a problem.I am liable and a consumer for your failures with your process. I must pay because u happiness wheel decided not to give me what I won and gave me an error. I am disgusted that I am treated like this. You are the only service provider available for my Grandmother that she enjoys, so I must tolerate the inability to service my accounts efficiently. I make payment on time yet you refuse to take ownership for your **** service. After your consultant confirm everything
