Poor service delivery on my sim card

I signed up for Rain around 3 weeks ago and received my Sim card a few days later. I received a message that night that said my sim card had been activated, well it wasn't. So I gave it 24 hours to activate and still nothing. Around a week and a half ago I decided to mail their support as there is no number to call them on due to Covid-19. I mailed 3 times in a span of the week to get this resolved with no luck.

I really want to use the service they have to offer but it seems they don't want me too.
