NO HELP FROM RAIN

October last year I decided to reactivate my RAIN account on the same device I had previously. It didn't work so I tried to get help to get it working again. I phoned numerous times. The problem is THERE IS NOWHERE TO GO TO. I wanted to take my device and SIM to sort out the problem. So I haven't been able to use my contract and despite, my asking for help and not receiving it, they are happy to debit my account. I demand a refund. Now when I try to cancel, they sms me to say the final payment (another payment besides the one TODAY) will go through.
