Borderline theft and insufficient support

Poor customer service and delay when cancelling contract. I had a contract expiring 7 April 2022 and instead of upgrading requested the contract to be cancelled and no further charges to be incurred. According to numerous consultants throughout a 2 week period it was confirmed contract will automatically cancel en of april and no further charges will be occured.

This morning, 11 May 2022, i recieved an new invoice and statements from vodacom indicating my line is on new contract and new charges are app****. This is absolutely unacceptable and borderline theft.
