Cannot cancel my service.

I've been trying to cancel my rain service for 2 months now. I've logged my first cancellation. Expecting my account to be cancelled only to find out it was not and I was billed for another month. I log a second cancellation and find out that I have to talk to an operator to confirm my cancellation (why this doesn't make any sense). Further to this I chat to an operator who cancels informs me she can only schedule a cancellation and I would need to chat to another operator for which I need to request an immediate cancellation. I confirm with them that my cell reception at work is non existent so it would be difficult for them to reach me whereby I requested a number to contact them. There was no available number I could contact to get an immediate cancellation. I'm now stuck in limbo going to be charge for a service I do not use for a third month in a row. I have on multiple times rep**** on my tickets without response. Rain get your act together and cancel my contract. I want a refund for the additional months I was charged past my original cancellation request.
