Vodacom didn't cancel my contract

I called the cancelations department on the 23 June 2020 and my cancelation was not processed and received a call from the attorneys saying I owe Vodacom. I went to the Vodacom Shop at Secunda mall in the 4 December 2020 and was assisted by Shadrack who was very helpful and tried to escalate the query with reference nr: ***. The service request was not attended to until my contract was deleted on the network and my account was handed over again to MBD attorneys. When we call the cancelations depart on the 15 May 2021. The gentleman by the name of Alesha Terumar couldn't assist as the account is on Legal status and gave a refernce: *** and told us to the accounts department. Im really disappointed as I did what I had to to make sure that the contract is cancelled and Vodacom doesn't want accept that they made a mistake and rectify their mistake.
