Vodacom contract

Can Vodacom stop *********** people, I have a serious problem with Vodacom contracts I***-2 this contract expired July 2021 and it's been over four months now trying to cancell but they don't wanna allow me to cancell even went to one of their branches in Hydepark & told me that Vodacom doesn't want people to cancell contracts so we need to call *** not *** that number you call the whole day with no help, so I decided to reverse my cash and Vodacom suspended services but i am still receiving the bills and now they claiming that I owe them over R2000.00 but they don't wanna cancell the contract, can someone please help me with ombudsman number because Vodacom is taking advantage of poor South Africans it's Covid 19 struggle we can afford them but they denying us to cancell that's unfair, I was told to call accounts regarding the bill & account keep on sending me to Voda cancelation and I am not getting any help.

Kind regards Jabu Thwala
