Vodacom is a **** !

If I could give -1 star I would. I have had a cellphone contract since 2022 till December 2025. I called them to cancel and the lady said it was cancelled and the cancellation would be effective on 31 December 2025, 2 months down the line when i tried taking a fibre line they tell me i owe R7 from the cellphone contact. I am given a reference number that i can only pay in store for it , I drive all the way to a Vodacom store to pay that balance and contact them and I'm told the account is closed they dont know why i had to pay R7. Now Vodacom is trying to debit money from my account 8 months after they had initially closed the account. WHAT DO WE CALL THAT?
