Unhappy Rain customer

I’ve been battling to cancel my rain subscription for over a month now,each time I phone they tell me my device is still active (which it is not) and they keep taking the money from my bank I have logged numerous calls where they promise to get back to me or email in 24 hours but no response. I requested a refund and no feedback has been provided therefore I would like to cancel all my rain subscriptions and a refund to be done
