STAY AWAY from Vodacom!!!!! WORST SERVICE!!!!!!!!

A 1 star rating is too much for Vodacom to even receive from me!! I am FURIOUS!!! I have been trying for months on end to try and get an issue sorted out on my account, and to this day, STILL NO RESOLVE!! I have sent multiple emails, phoned in numerous times and I just nowhere with them. They have been debiting my account for the following:

1. A contract I CANCELLED with them OVER 2 YEARS AGO 2. Two contracts which were supposed to switched to prepaid at the beginning of 2020

I have sent them a breakdown (in spreadsheet format), showing ALL the debits which need to be refunded to me. I have emailed them my issue time and time again, yet ALL I receive is an automated response telling me to respond with my contact and ID number. Bearing in mind this has always been provided in all the lengthy emails I have sent to them. No one ever contacts me back!!!!!
