Vodacom service sucks

Took a contract with Vodacom on April 2020, in December I saw on my app a 1gig recurring WhatsApp Bundle that made an increase on my monthly payment. I do not have WhatsApp on this device and I was told that I bought the bundle using USSD code. In Jan 2021 the agent that I spoke to said she will cancel this from her side and then my monthly repayment will continue as normal. Again this month samething R733 will be deducted from my account instead of R698 my normal monthly repayment. Phoned client care today spoke to team leader she said she will listen to the recording between myself and the agent that said will cancel this recurring WhatsApp bundle that was activated on my number. Her feedback was that the agent never said she will cancel the recurring bundle. I then asked for the recording the team leader said unfortunately I have to make time and listen to the recording at any Vodacom store. What **** is this? I'm so over Vodacom. Why would I purchase a WhatsApp bundle where as I do not have WhatsApp. Now I'm paying for something that I did not do. This month I must pay extra but I was told that this thing was canceled
