RAIN deducted money from my account and then blocked my account

I bought a rain sim card via Mr Delivery on 24 June 2020 and was delivered in less than an hour. I then went to their website to follow instructions on how to activate and rica the sim. I managed to activate the sim but was then required to insert my credit card details so that R479 can be deducted before I could proceed ro RICA. My money has since been deducted but when logging in my account, it wasn't reflecting and was showing that my account will be cancelled after 7 days if I didn't make any payment. I sent several messages on the Rain website but none of those messages received any response, my account has even been cancelled.

I'm very unhappy, frustrated and disappointed with their service. I thought getting their network will make my experience of working from home easier but instead I regret the day I ordered their sim card. It's been a month now and no one has assisted me but yet they have deducted my hard earned R479 especially during this time. I want my money back, I can't allow Rain to **** me. Does anyone know how I can get them to respond to my messages and then refund me?
