Bullying and taking people's money unauthorized

I cancelled my contract which was coming to an end on 30 April 2020 with cell c. It was a lot of struggle to finally get hold of cancellation department as lock down had recently started and each time I called, customer care would tell me that they had sent an email to cancellation department to get in touch with me as they are working from home. Finally after many attempts of following their process, I got hold of cancellation department who then assured me that my contract is canceled. After this process, my last debit order date was supposed to be on 15 May 2020 with the amount of R241.00.

On 15 June 2020 Cell c debited my account with the amount of R504.08 unauthorized, I then reversed this amount which cost me R40 for charges as at this point i don't have a contract with them. They went again to debit R504.08 on 25 June 2020. Then I called them on the same day and was told that my account is active. At this point I an confused because cell c told me my account is canceled then they come back again and tell me it's active and they will not cancel it as I am owing them (the money is not cleared), what??? I asked the agent to please get the phone recording of my conversation and reverse my money. At this point it seems like it is so impossible to do that, he tells me that he has escalated my query to the relevant department and he gave me a long reference number ( only to later find out that number is not even reference) and tell me another reference number will be SMS'd to my alternative number I gave me.

On 26 June 2020 I received a call from cell c only to request my ID number and when I asked the lady about the status of my query she told me that she is going to investigate and will come back to me, just that.

Now yesterday, 02 July 2020 when I followed up customer service told me that on29 June my contract was cancelled effective from 25 July 2020, what?? So what happens until then? Are you gonna continue to take my money forcefully? They way she was so rude with no remorse to my situation, she then said call cancellation department as they sent you an sms that you must call them for further details. At this stage I am more confused, what sms? She said an sms was sent to you data number that was forever on the router and that is canceled, how would I see that? she said, well that is your responsibility to insert the sim card to the mobile cell phone device to check sms's, call cancellation because I will not even transfer you, yoh!

I again called cancellation who confirmed what Customer service lady said. They will debit my account again on the 15 July irrespective of the fact that the contract was canceled as per their terms and conditions of the cancellation clause. They told me the call record is still not been sourced, they apologies for the inconvenience. At the moment they cannot do anything for me, I must again call then after receiving statement to query the invoice, this call took an hour to just get this outcome.

This is the worst form of abuse I have ever seen in the entire 38 years of my life. I am financially inconvenienced, calling them drains me emotionally, like I am forced to continuously go back to the abuser. They do not take any responsibility for this mess, clearly someone did not do their job properly and I am being punished for that. I just want my money please.
