OVER 48HRS LATER SIM SWAP NOT ACTIVATED YET

I went for an uograde on Saturday morning, 14/03/15, and had to do a sim swap as well. I was told it would take 2 - 24hrs in order for hte sim to be activated. Sunday morning, exactly 24hrs later, it was still not done and I then proceeded to call the Customer Call Centre om ***. I was told it was not done at the store and that they would now do it manually from their side and would take another 2 - 24hrs. Well, this morning, 16/03/15, it is still not done. I went to the MTN branch in Malmesbury where they proceeded to call the Customer Care Line again. They were then told a USD needs to be logged: Node to Node Failure as the activation at Bayside was not done correctly and it would take another 2 - 24hrs. I'm sorry to say this but MTN can close their doors...I never experienced a smooth upgrade and I am extremely upset as I cannot rely on my phone to work because the other sim still works but my data is gone. So what the hell am I supposed to do now.
