Ridiculous Service

I cancelled my DSTV account for the month of March and reactivated it about 5 days before the end of March. I've been calling Multi-choice for the whole month of April because my account has been suspended about 10 times. Every time I call in I have explain the situation to a new agent(using my airtime) and all they tell me is that they are INVESTIGATING the matter and for a day or so my account gets re-activated only to be suspended again. I've sent statements showing that I last paid at the end of February and they keep telling me that I was refunded the amount that I paid in Feb which I wasn't. I paid about 450 for April and prorata for March, which I think is also too high, as it was supposed to been the Normal compact rate as well as daily charge for the 5 days in March. The issue here is that to this day my account keeps getting suspended which is ridiculous because I spoke to two supervisors and they also keep telling that that they'll investigate the matter from which I've received no feedback!! it's unacceptable that I have to keep calling DSTV only to be asked for statements and be told that my matter id being investigated when I've been making payments as I'm expected to, yet no one cares to give me the courtesy of a call or email to let me know what the outcome of this investigation is and either way I have to keep making payments to them. I want a this issue sorted out and my airtime back.
