LOSING IT WITH VODACOM

If ever there was a 0.5 rating to give Vodacom, they would have received it for mere existence. i am so livid with them. on April 27 i wrote to customer care services FOLLOWING UP A CANCELLATION... I REPEAT...FOLLOWING UP, NOT STARTING. 4 Months later today here i am still being billed on services that i have said to please be cancelled. i have called customer care, spoken to supervisors, written emails, walked into one of the shops and everyone cant get it right to just cancel a contract...a contract which has finished. All i want to do especially in the covid times is to reduce expenses but vodacom clearly have not received that memo. they do not care about the poor customers who are just trying to save some money. Nooo they want to bleed me dry. I honestly felt like crying when i saw an email statement come in with a new invoice for August. what do i need to do? all i want is to cancel this service. And get this i am not even using the airtime and data they are sending me!!!!! I dont know what to do!!! Vodacom do you receive cancellation by smoke signal? Morse Code? Rocket ship? And i am a really nice person.
