Vodacom Crisis

literally the worst service ever! I am applying for a homeloan, my transunion report score me low, Vodacom claiming I owe them over R6k. After many painful phone calls, this is where I currently stand. I was upgraded in 2023 on my MOBILE contract without MY consent, my statement is a mess and no consistent billing, never mind I was NEVER notified that there was an issue either, or invoices and statements sent to me. Out of desperation I pay them, then the next day I call again, now the money is lying on the Fibre account days later they say its fine now. Today I call for a letter stating that my account has a 0 balance and that they have no objective to update my transunion profile. But here I am they telling me - I cannot get a letter like this, I must close my entire account - so its an issue for a payment made on my account number thats apparently not the mobile account, but I cannot get a letter, as I must close everything? How does this even make sense. Oh wait there is more, apparently I also cancelled my fibre account on the 23rd of September. Its absolutely mind blowing how ridiculous this situation is. Perhaps the next step I should take is court. Vodacom definitely owe me money, I never wanted to cancel my fibre account and I just want my name cleared from Transunion.
