Vodacom - Bad Bad service with a pathetic and unprofessional accounts department.

Bad Bad service with a pathetic and unprofessional accounts department. I have been a client with Vodacom for more than 10 years but for the last 3 months experienced such bad service and zero assistance it's unbelievable. My contract package expired in December 2018. Stay on the package on a month to month basis till May 2020 with my account paid up in full. Contacted Vodacom in the beginning of May 2020 and requested them to cancel and move to a Vodacom pre-paid account. I called Vodacom customer support 8 times and went to the Vodacom shop in Somerset-West 4 times but they still keep on with the debit order each month after May 2020 and still do not want to move me onto a pre-paid package. They send me from one costumer consultant to another and each time promise that my debit order was cancelled and that my package was moved to pre-paid and each time VODACOM LIE and DECEIVE me.
