Still not router delivery and old data cap

Upgraded LTE contract through Telkom mobile over the phone.<br> Promised delivery of router within 4 business days. Still getting capped on my old data cap and still no router delivered.<br> Client services keeps referring me to the sales department. Unable to reach the sales department through any medium. When phoning the sales department phone number you just sit on hold for hours before being disconnected. Multiple promises from other departments managers that the sales department will phone me but it never happens. It has now been more than 3 weeks. Hands down the worst after sales service I have ever experienced.
