Most Pathetic service ever and refuse to cancel contracts

Vodacom has the most pathetic service ever. I have cancelled a data contract with Vodacom in May this year and still the contract is not cancelled. They are deducting money from my account every month despite the fact that I requested cancellation. They supposedly save their call recordings but are unable to provide customers with same, which is very strange. They do not follow up with queries and transfer you from one consultant to the next. They also refuse to transfer you to a manager or senior manager. By taking money from me you are *****ing from me and you are acting against the Consumer Protection Act. This is completing ridiculous and I want my refund since date of cancellation. I am going to place my complaint on all social medial platforms because people must be made aware before entering into any arrangements with Vodacom.
