Impossible to cancel Rain sim.

On the 21/04/2025 I received a call following a cancellation request. The consultant confirmed that my sim with be cancelled from 01/05/2025. Only for my account to be debited not on for May but also in June. Since the initial call I have not used any data and the records can be checked. I went online on 27/08/2025 and followed the cancellation prompts and received the OTP only to receive an sms today saying that my debit was unsuccessful. Logged into my profile and a charge for September has been raised.

I'm not going to pay for any further charges and require a refund for May and June as cancellation was confirmed by your consultant.

Require somebody to call me urgently.
