Telkom Unlimited LTE Broadband

I app**** and was accepted for the R599 per month deal. I was told by the call centre that 5 - 7 business days after the first debit order went through, my LTE modem and SIM card would be delivered to me and to be ready with the RICA documentation. I then had to arrange for installation. It's been more than 3 weeks since the debit order, no sign of any delivery. I have contacted them again (twice) to try to find out what's happening. No response.
