Cannot cancel my Rain

I have been trying to cancel my Rain since 1 December. First they said someone will phone me but they never did. Then out of desperation I got through to an agent (don't choose the option to cancel your Rain on the phone as they put you through to a third party that only promises to get an agent to phone you). Then I resorted to suspending my account. I had an arrears amount and they said that they would not debit my account on the 15th of December. They still tried. Got notification that my Rain termination was lifted as soon as I suspended my Rain. On 15 January (my debit date) all my arrears tried to come off and bounced - Then on 29 Jan when I received my payment all my arrears came off. When I go into my app to cancel it diverts me to Rain Go where I am suppose to cancel it by clicking on the simcard. There are no simcards listed there and my address is wrong. I need an agent to contact me to cancel my service or my negative online review here will remain.
