Bad/non-existant customer service

I'd like someone from RAIN customer care to please contact me via email please. I have sent numerous mails and have been trying to get a hold of you for almost 6 weeks now. I took a RAIN LTA data SIM before lockdown and was billed twice as there was a problem with the website when buying the SIM online. I tried contacting you for a refund. I'm still waiting for someone to get back to me. Please advise soonest. Thank you.
