Urgent Assistance Required

I've ordered their uncapped prepaid F-LTE on Friday the 13th August 2021 and have already made payment of R999 on the same day but have not been assisted with my order, no one responds to emails or the WhatsApp line. I got told that my orders on hold due to a debit order mandate which needs to be completed but there's no option on the portal to complete the mandate and no one is able to send me a mandate form to complete. Can someone from this company urgently assist because I am done begging for a non existent service that I've already paid for. If this can't be corrected then I'd urgently like to have my money refunded and find another ISP that actually wants my business.
