Must pay for something which is not working.

I Signed up for a Rain 24/7 Uncapped. I never had a proper connection "I COULD NOT HAVE USE IT" I got the best speed was 0.47Mbps. I called (Rain not taking calls because apparently Coronavirus can spread though a phone call) I emailed there support team, Logged Support Tickets on there website. I even send them Facebook messager messages. No Feedback from Rain. So I cancelled the Product because since I cant use it and rain doesnt assist customers. I could not see why I should be continue on like that. Now They want me to pay R411.00 for no service

I will not pay for something I could not have used. If you dont remove the alleged outstanding from my account I will contact ICCASA.
