Vodacom poor service and lack of willingness to help.

I have a fiber subscription with Vodacom since 2018, the fiber has been working fine since i had started with them, but the issue i have with vodecom i once had a missing payment last year July (2023), i did pay the missing a monthly later. but in September 2023 Vodacom happened to debit my account and that was picked up by a staff member (Nandipha Andrew) in February 2024 when i called wanting to log a complaint (Ref number: SR***) because Vodacom flagged me on credit bureau claiming that I'm in 1 month arrears and i dont have any arears on my account , this issue is really frustrating because every month my credit score decreases every month because of vodacom, i dont know mow many times i called vodacom seeking help in this situation and everytime im being taken from pillar-to-post with no help. biggening of last month (May 2024) i called vodacom cancellation department asking them to cancel my subscription with them because i thought thats the only solution. the lady that was helping, asked me not to cancel and her manager is going to handle my situation and they promised to rectify the error that is made by vodacom on my profile from credit bureau, but to my surprise my credit score decreased again this month due to 1 month arrears that vodacom claim that im in. Vodacom is affecting my life. i want to cancel the account with them. why dont i get help from such a big telecom entity like vodacom.
