Cartrack is really becoming a PAIN, and the worst in resolving customers issue relating to money

Cartrack is really becoming a PAIN, they keep debiting my account for amounts that I don't owe and never even agreed on. Now my policies are bouncing because they took a whole R1000.00 that was reserved for my life cover, home insurance, and funeral policy and I don't even owe them that amount they never communicated. I have paid the cancellation fee but no they keep coming for my account. Last month I had the same issue, the last communication was after I sent a review on here, and 1 of the consultants said they will call me to escalate and I must wait for a call on the day or the latest the following day, till this day they never called. I called again today regarding the R1000.00 they saying they will escalate again and after that, for them to pay me back it take 7 to 14 days. in the meantime what happens to my policies?
