STOP IGNORING MY CANCELLATIONS REQUESTS & STOP DEBITING MY ACCOUNT

My cellphone contract ended in February 2020. emailed cancellation of my cellphone contact and cancellation of the contract in December 2019. Cancellation for contract was ignored because it was debited in January 2020. I then phoned in January to repeat cancellation of insurance & cancellation of the contract. The last debit order for February was correct WITHOUT the insurance. In March my account was debited including the insurance, i stopped the debit order because Vodacom has no rights debiting my account when the contract has ended and after i have cancelled the contract. The contract that ended in Feb 2020. From March after my end of the contract i have no business with vodacom. Today 15 May 2020 my account was debited again including insurance. This is sick and unacceptable. Telkom, CellC and MNT never gave me this round-around nonsense at the end of the contract. What is wrong with Vodacom? I am very ****ed off!
