Bad client service from Vodacom

Account no’s: I***-3 and I***, Cell no: *** Dear Vodacom, I am writing to you as I have run out of options and patience in contacting the Vodacom client service call center to get my problem sorted out. I briefly give the sequence of events that led to the problem: 1. On 15/01/2021 I contacted the call center to cancel my contract on cell no *** with the specific instruction that I would like to keep the number for data services only and that I will be responsible for purchasing data on an as and when required basis. This implies that I will not receive any invoice for the above mentioned cell number, 2. When I received my statement I discovered that an amount of R149-01 was charged for Any Time Data. I specifically did not request Vodacom to supply data on a contract basis for cell no ***. 3. I subsequently phoned every month to complain about the problem every time with the promise that it was cancelled and the problem with the overcharging of monies will be sorted out. 4. The call center was contacted again on 26/04/2021 with the explanation that this was an old contract on the M2 system and that upgrades and cancellations cannot be processed due to a system error. This explanation is totally unacceptable in my view for a first world communication company. 5. On the latest statement dated 04/06/2021 the overcharging of monies on cell no *** was still not sorted out. I request you to please assist me in sorting out my problem. Thank you, Marlene Vilonel Cell no ***
