Poor service delivery and I want my money back Rain

I created an account in April and the card arrived in May. I have been emailing since requesting assistance to get it activated and never received any feedback. I have been debited for a Sim that is not even working. I've since asked that I be refunded and contract be cancelled and still no response. We are heading towards end of July and I better not be debited again for an inactive sim. This is ridiculous and and unacceptable.
