VODACOM IS ***!

I am disgusted with Vodacom service, I cancelled and paid up my contract in 2021 which cost me over R8000 I sent through the info to the cancelations department just to find that in 2022 it wasn't cancelled on their side, I apparently owed an amount of 700 which I queried then my account was finally closed and put on prepaid now in 2023 I owe Vodacom over R3000 which I don't understand because I cancelled and paid my account in 2021 already! Today I sat on the phone with Vodacom for 3 hours to be transferred from pillar to post still for my query not to be resolved! this R3000 is now reflecting bad on my ITC report! this is ****************! as far as I'm concerned I DO NOT OWE VODACOM *****! my account was paid up and paperwork was summitted for the contract to be cancelled in 2021 already! SOMEONE PLEASE HELP ME!!!!! THEY JUST WANT TO MILK AND MILK AND MILK!
