Bad service from Telkom

I order a wifi device online from telkom and recieved it on Monday 28 Augustus 2017, where after I phoned Telkom call Centre (081180) to activate my sim card where it was promised that it woud be activated in 48 hours. I waited 48 hours and phoned again where I was told that they will log a call to activate my sim card (call ref no: ********** 7) and that this will take another 24 hours and I waited. Now it has been 73 hours and still the sim card is not registered. The ladies at the call centre says I must speak to the sales department to activate it and the sales department says I must speak to the call centre. The branch in Rustenburg is also unhelpful because I did not order it from them. What am I to do now?
