Billing

I am so dissapointed and I have no words to explain how I feel , I am furious with Multichoice , yesterday they switched off my account with them after double debiting my bank account on the 20th without my instruction and when I call the call center the agent tells me that they made a mistake and I will have to wait for 40days to get the refund , I am not happy with the service because when I call in the agents are not telling me the same thing and as we speak I am not watching TV which I paid for on the 23th Feb .I need answers from some one else and not the agents because seemingly they dont know what they are doing, its pity I didnt take down their names because I called in again today waisting my airtime talking for 30minutes and still no solution.
