Vodacom and it Contact Centre will never help you

Vodacom and their agents are not willing to assist customers i called them seeking help and they told me to downgrade today they are telling me to call number that is not even a vodacom number and hey still can not assist with why my bill kept changing every month, from 2021 my instalment has been changing and they do not reveal all the information to their customer. Their agents do not know their job Nonjabulo Ndlovu couldn't assist me in july but she made my account even more messed up. i dont want anything to do with them
