Vodacom pathetic service

My husband had done an early cancellation on a data contract as we have been having a melees issues with Vodacom. We were paying for wifi however we were not able to use it and for months we have complained telephonically and via emails, an employee was sent to test it out at our home and could not understand what the problem was. Till today no one has contacted us. Therefore we have done and early cancellation in December 2022 made the payment emailed the proof and quote that was sent to us giving us the amount to pay and instructions on what to do. All done after 2 weeks I called to check if it was cancelled and it wasn’t I had to resend everything to another email but now he is still being billed. So Vodacom you can continue billing but will never get a cent from me we can go to court about his also as I have proof of everything. Soon my other 3 contracts that are due to upgrade will also be cancelled.😡
