Complaint about CellC account department.

Hi, i have cancelled my account with CellC on the 18th February 2020, it was a data only contract, they said i must pay in the outstanding amount, which i did. After contacting them again they send me a confermation SMS saying it is canceled. At the end of the month 29 Feb they deducted R46. 01.So i thought it was over. But on 31March they deducted the full amount again, i had to reverse it, then on 15th April they deducted the full amount again. Which i had to reverse again. So now I'm wondering how long this will go on, i have been there before with GloCell and it went on forever till i closed my bank account. Can't do that again. The call center is closed due to the Corona Virus so no help from them. Thank you for listening to me.
