Vodacom unexpected debit order increase

am loyal customer of Vodacom. I have been with them for so many years. Now I'm pieced off after one of the staff member called me to tell me that I'm due for upgrade. I didn't take up any upgrade over the phone, I told the staff member that I'm much aware of that however I will review my account and go to the branch knowing that I have to cancel some of the numbers that I don't really need. I'm suffering even R560 that I'm paying is still paining. August I was out of country from 20th I didn't notice of any change, today I see R2293 went off my account as a surprise. When i went back to check last month I see R1650 was debited. Someone *********** who is selfish , who don't care about customers decided to upgrade my account without my concent.

I want my money back. I want to cancel all Vodacom accounts I have. I will move to any other service provider. I want disciplinary action to be taken against the staff member who costed me so much. Must I suffer because someone has a target to reach. I want recordings of call and contract if Vidacom says I have taken up the product. I have been suffering 😭 financially which I ended on Depression. How can I take up extra products. I know my income and expenses very well. I'm not that stupid. But if someone think they are clever enough. The person must face the consequences.
