Vodacom is a nightmare!!!

Vodacom is the worst service provider when it comes to receiving assistance. My nightmare with Vodacom started June 2023. Vodacom tried to debit my account for 3 times the amount stated on the contract and this flagged on my bank accounts. The debit was reversed as this was an incorrect amount. There after they did not debit the account or contact me regarding this. The contract was due to end in December 2023. I contacted Vodacom and requested to cancel the contract however I was told that there was a balance to be paid according to their system. I agreed with them as they did not debit my account for the balance of the contract. They advised that they would send an email to the cancellations department and request the contract to be cancelled. I was given 3 different contact numbers to arrange payment for the outstanding balance however this did not work as they had blocked the contract number and it did not allow me to proceed with contacting any department as the virtual operator stated that my number did not exist. After numerous attempts since December 2023 I finally managed to contact the collections department who informed me that my account was handed over ( is this even legal? How do you handover an account without contacting or attempting to contact the customer?) further to this I was advised to contact their legal department who requested I contact a debt collections agency. I sent numerous emails and tried contacting that agency however once again I received no response. I contacted vodacom legal again they provided me with contact details for a new debt collection agency. Which is now claiming for R6000. I have been requesting a detailed statement regarding this balance and all i have received so far is a statement for R6000.... Outstanding balance on contract R2000 and a payment of R4000 for subscription for mobile communication. Mobile communications that have been blocked from July 2023??? This is the worst network provider to get into a contract with. They are refusing to accept that they made a mistake or to even rectify it. This has been a complete nightmare and I will never use this service provider or refer them to my friends and family.
