Bad service and dont cancel contracts when requested

Vodacom has shown a willingness to contact me repeatedly for sales and upgrade opportunities, yet has failed to process a straightforward cancellation request for contracts that have already expired. I have spent considerable time making repeated phone calls, following up on promises made by Vodacom consultants, and attempting to resolve this matter directly with the service provider. The continued deductions after my cancellation requests and Vodacom’s failure to respond to my complaint have caused me financial prejudice, inconvenience, frustration, and a complete loss of trust in the company. I believe Vodacom has failed to: • Act on clear and repeated cancellation instructions; • Process cancellations within a reasonable time; • Communicate honestly and transparently; • Respond to a formal customer complaint; and • Treat me fairly as a consumer in accordance with the Consumer Protection Act and the principles of Treating Customers Fairly (TCF). I have logged a complained with the complaints department and no response even.
