Debit- rain cancellation

I cancelled my Rain subscription before the 15th May 2025, my connection was cut immediately after that. At the end of May I was debited the full amount, after numerous emails I sent online I never got any feedback. I later got hold of them early June telephonically and the agent advised that because I still have the device they need to bill me but they never collected the device after I've asked them countless times to collect. This morning I was debited again and I don't even have the device. The device was collected early June as well.

Please note the reason why I cancelled my subscription is because I can no longer afford it but Rain has been deducting from my account for 2months now and I don't have the device and my connectivity has been cancelled the minute I cancelled my subscription. I have been using Rain for 5years and I never knew how difficult it would be to cancel with them or get any assistance and feedback
