I cancelled my cartrack account in April and paid my cancellation fee but my account is still being debited monthly and now when I called in I hear that I called again and requested a re-instatement on the same vehicle I clearly stated was sold

I cancelled my cartrack account in April and paid my cancellation fee but my account is still being debited monthly and now when I called in I hear that I called again and requested a re-instatement on the same vehicle I clearly stated was sold. The consultant that assisted me on the 29th April didn't capture my instruction correctly and now I hear that I'm liable for another cancellation fee. This is totally unacceptable and I will not pay Cartrack any money. I'm appalled by the service I'm getting and would like this matter to be resolved. I was happy with the service received from Melicia Mudau today, she said she'll escalate the matter and request for a recording of the call from the 29th April
