Pay back my money

Sometime in June 2025 I upgraded my package with Rain. I was of the view (based on the advise of the agent) that since it's an upgrade the old one will automatically lapse. To my surprise both contracts ran at the same time and was charged for both. I called in and was told that I didn't cancel the old one, and then advised the agent to cancel the old one. A day later I had no service on the new router - 2 days passed, I called and was told how to troubleshoot. That also didn't work. On the 3rd day when I called the agent informed me that the new contract has been canceled hence I had no network. So the agent had canceleld the wrong one. She told me the old contract was also canceled and I had no contdact with Rain according to the system. Since i had paid, i asked for a refund and was told i will be reimbursed +-R350. To my shock my account was debited with R269 or so. I called again, explained once again the entire saga, hoping for a resolution, since it was a matter of principle. Since I was informed that i did not have a contract with Rain, and needed to restart the application process, I went and sourced another package from another provider and secured one. I am still using that provider. Shockingly Rain continues to debit my account I have called, used chatbot, emailed to no success. Reference numbers are just useless. I need to be reimbursed, since my contracts have been canceled and not by me but the incompetence of their agents. I am happy with my current provider and have no interest in reinstating my " canceled" contract. I sent an email on 1 July - no response.
