Seven days for SIM activation???

I Have received my package for a new LTE contract on the 9th of December 2015. The Telkom Consultant sent me an email with all the numbers that I will need for activation of the device as well as the SIM card. On the 09/12 I received a call from the consultant for SIM activation, however, when I checked the SIM it was not activated. I then called all the numbers that the consultant provided and no one could help. The ***/7400 rings with no answer at all. The consultants on this number: 081 180, keep diverting my call to the above mentioned number with no answer as well. The new contract has a seven days cooling period which has already lapsed. Will I still be liable if this device if its not in working order?<br> <br>
