VODACOM THE MOST INPOMPETENT!!

I have been with Vodacom from 1996 and was very happy with their services until recently. I arraged for my grandson, who at that time studied at PE University to have a fibre line installed as he was struggling with WiFi. All went well, got it installed and the contract was for 1 year, was suppose to end at the end October 2020. As a result of Covid 19, he had to move back to George where there is no fibre availabe. That was two months before the actual end of contract and even he did not used it until end October 2030, I still paid for it. At the end of October 2020, I sent an e-mail to cancel the contract. Between that date and now, I sent the cancellation e-mail with request to cancel it with immediate effect, three times again, but with no luck. I am fed-up now. These peoe are just plane ******** or ***********. They egnore my cancellation and every month I still get an invoice. If I do not pay, they stop my phone services which is linked to this account.
