Rain taking money out of my account

I am utterly disappointed at the rain business, yesterday without even contacting me or an agreement they took money out of my account twice, it was to my understanding that if a customer does not pay then the service are closed till payment is made however to my surprise even though the service is closed for months I am still billed (for something I am not even using) , and the worst scenario this is not a debit which I can reverse through my bank but rain had made as if I purchased something and have billed my card to get the money.. My bank account sees it as a purchase I have made and not a debit how is this possible and worst of all when you contact rain you wait long to get through customer services and they cut your call
