Vodacom funeral cover disgusting service!

I’m hoping that this review will get me some much needed help. Once again Vodacom disappoints. I’ve requested that the funeral cover I have with Vodacom be cancelled in May 2020 already. I’ve spoken to 2 agents from that department who have promised to cancel it, yes I get billed every month. I stopped paying the cover for the past 3 months with the hope that someone will assist. With more than 10 calls to customer service, who transfer me to ***0 who keep promising to assist. The last person I spoke to was, Bongumusa Biyela, who also said it would be cancelled. No ref given, as they don’t give reference numbers. This was on 27 July. Since then I have received 2 calls from agents asking me if I’d like to take out Vodacom funeral cover!!!! REALLY? I said I cancelled and they said they can see that on the system but I keep getting billed. I just don’t know what to do anymore!
