Worst Customer Service Experience from RAIN

Bought a magaziner with a rain sim, was so happy until I had to activate it. I have lost my ID, and due to COVID-19 and cannot issue a new ID. I have a valid SA Passport and Driveder's license and temporary ID, but I can't use any of these to RICA my simcard online. I have sent an email but there's no response. I can't even cancel this sim card, so that I can order another 1 to conclude the RICA stage.
