USELESS SERVICE DELIVERY

On the 8th of March 2021, I received an SMS that Vodacom had handed my account over to VVM debt collectors for lack of payment. To my knowledge, the account had been settled previously and I have since been sending emails and proof of my innocence to both the Vodacom Legal team as well as VVM Debt collectors. I have accumulated over 10 different reference numbers, of which not a single one has been looked at. I've been in contact with VVM who keep referring me to Vodacom, and I have been in contact with Vodacom who keep referring me to VVM. I receive calls every day from VVM to inform me that I owe them money, I explain the situation , then they promise to escalate my case so a person can contact me and clear the situation up, This never seems to materialize and I'll only hear form them again when a different consultant phones to inform me of the outstanding balance. I have been trying to get a response for over a month, I have sent multiple emails and phoned multiple times, This includes sending follow up emails where I try and get feedback on the Reference numbers given to me previously, and have not received any feedback, clarity, or any support whatsoever. UTTERLY USELESS SERVICE DELIVERY!
