SHOCKING VODACOM SERVICE - take R40 pm from contract *******ly from pensioner

Vodacom subtract R40 per month more than my contract value from my bank account for the past 8 months. I Phoned Vodacom on 29/11/2019, 02/12/2019, 06/12/2019 and sent them an email on 09/12/2019. The reply on two phonecalls was that Vodacom is wrong there is a problem. The feedback from the third call was that there is no billing problem. The reply on my email complaint from Vodacom was that there is no problem with the amount that is subtracted from my account. On 10/12/2019 I received a phonecall from Vodacom (Jeremy Meyer) and he confirmed that Vodacom is indeed subtracting R40 too much from my account. I am again in the process of waiting................ This issue is a fact that Vodacom takes R40 pm *******ly from a pensioner that cannot afford it and so far do not recognise the problem, whilst Vodacom’s COO earns R38 000 000.00 per year. All I can say is that it is shocking.
