Bad Vodacom!! I will never ever refer any one to them ever

I got a account with Vodacom for 23 years !during the lockdown my money didn't go in on time , and Vodacom cut my phone off. I paid it and it took them a week to put my phone on again. I contact Vodacom to cancel my contract in beginning of September for the end of September to go on prepaid . It wasn't cancelled I contact them again and again and again and it is still not cancelled .They just don't give a ref no, or any thing at all, no feed back Im spending hours on the phone with different people and still it isn't cancelled we are now on the 16 of November 2020 and Im still try to go on prepaid
