BAD SERVICE I AM GETTING FROM RAIN INTERNET SERVICE PROVIDER

I have been sent from pillar to post by the not so helpful rain customer center officials. They have debited my account on the 17 April 2021, for the amount of R479. The simcard which was delivered to me is not linked to the payment, that is what I am told by the call center agent. I was advised to request a sim swop. It is almost two months calling them without getting any joy. Hello Peter, please help.
