Overcharged, no cancellations logged, no refunds

I tried to give a month notice in April as I was moving end of May. They told me to cancel my subscription in the month I would like to cancel. This was never logged. I was charged an additional two months for a service that was last active mid May. After numerous calls over the past month, only one call was logged. I am due a refund of two months and still nothing has been done about it. Problem is you make your first payment with a card, so they just debit that card every month. I couldn't cancel it with the bank. I suggested Rain to so many people but will most definitely never ever make use of them again.
