Delayed Feedback

I went to Telkom Southgate and The Glen in December 2015 to buy a MiFi router. It was unavailable. I have gone various times after and each time they had no router. I have a Telkom data sim on Month to Month which i couldn't get with a device. But I am now sitting with a SIM card that I can't use. When I ask at the shop's they do not know if or when they will have routers. I then went onto Twitter and asked for assistance from the social media team. I asked if the router has been discontinued and what other options I have. This was on the 3rd of February 2016. I have not got a response to date. I keep asking and they keep saying they will follow up with an update. I have screen shots of the messages. This is incredibly disappointing and inconvenient. I am a freelancer and I got this so that I do not have to go to Wi-Fi hot spots to do work I can do at home with my own WiFi.
