Vodacom Contract Cancelation

Hello all. Ones again Vodacom is buzzy with there tricks. On 17 Feb 2021 i called there cancellation department to cancel my one contract. 28 April 2021 i called them to confirm that the contract is cancelled and that there will be no debit order going off just to find out that the cancellation was never processed. And according to Ms Hlengiwe the cancellation was never submitted. The debit order still went off and there is still no confirmation that the contract is cancelled. on request to speak to a manager it was refused. now can they go on like this as i see this as *****. and this is not the first time I'm having this problem with them. They are fast to get the contract signed and collecting fees. but come to cancellation it is always a struggle. cant even give reference numbers for the call. just saying today's date is the reference number.
