Vodacom is no help. Worst providers

My partner and i signed up for a contract with Vodacom @ game in Kolanade Mall in 2019 February for a Cell Phone and a Game Voucher airtime that comes with it for 24 months. The Cellphone was then ****** in the same year not to long from taking the contract out. Our Contract was suppose to end in March 2021 as it was for 24 months. We had not been contacted regarding the renewal or Termination of the contract even though Vodacom has our contact details that we submitted when we app****. upon further noticing that they continued to debit our account long after the contract should have ended we attempted in May 2021 to cancel and they did not comply and then had an written cancellation and still without prevail they continued. VODACOM ARE ******* . Up to date we still have no communication regarding our cancellation and refund as it is *********. Vodacom please pay me back my money or i will take legal action.
