Rain double Debit my account for a Router service I do not have.

Rain decided to double debit my account, I cancelled an old router in June 2025, ordered a new router Rain101 on the same month. they still charged for the old router that stopped on working on 30 June 2025.

I called them end of June to request them to refund, which they did. This morning they did the same thing of double debitting my account again. this is tiring to call a company to fix the same problem twice. that means I am going to have the samee problem every month, I cannot be calling rain about same thing every month. I want my money back and they can start the cancellation process for second router as well. I have enough with RAIN
