bad service and refusal to stop debiting account

To whom it may concern

i have been granted a bond by standard bank through betterbond originators around 2014. hence i took out an insurance policy with betterlife(a division of betterbond) with them for R200 just in case something happens to me as its compulsory to have insurance when you take out a bond and its understandable. I then managed to pay of the bond two months ago after four year. I then contacted better life to cancel the insurance policy as the bond is paid up and i dont need it which they said they would over the phone but they didnt. This are still debiting my account after me telling them to stop twice. i even sent the documents to them that the bond is paid. i need them to stop debiting my account.

name :raven jimmy id: ********** 126087 debit amt approx R200

please assist and thank you
