LTE SIM NOT AVTIVATED

On Saturday the 1st of August 2015 I took out an LTE 50GB contract from Fourways Mall Telkom. My sim and router was handed to me. When the lady tested the Sim in the device the sim was not registered on the network. I was told that I must wait a few hours and then test again. On Sunday the 2nd of August the device was still not working. I went to the telkom Shop again and the lady told me a diffrent story about I have to wait 12 hours and that my sim would be activated on Monday. She said that she will phone me and give feedback on the problem. SINCE i left I have had no call from their offices since saturday. It is now Monday 3RD August 3h30pm and the sim has not been activated and registered on the network yet. I have phone their office since this morning and they simply dont awnser their phone. I have even phoned the mall managament and they directed me to diffrent number than advertised on google. Still no employee/agent phone me regarding this. This is extremely bad service and this will let me think twice in future to look at any deals from Telkom.
