PATHETIC!!! Nothing working!!!

I did a sim swop on Tuesday and everything worked that day. Yesterday morning it stopped working and I have called numerous times to try and resolve. NO SERVICE!!!! I have been told that the sim is locked, they unlocked it. Still not working, I have been told that a back office is going to resolve it, still no joy. I have just received pathetic service from the call center, they tell me that the system is offline now. did not want me to speak to a manager and dropped the phone in my ear (the lady's name was Lindi). I am sick and tired of hearing that there is nothing they can do for me. It is not my phone settings, I did try the sim in another phone and inserted the other phones sim into mine, the problem is with the sim. I tried to purchase data because it started to give me HSDPA which only works sometimes (I have an LTE device). It tells me: provisionVASfailed:>MSISDN*** is deactivated. So my question is who the hell is going to pay for my out of bundle rates and when is Vodacom who does not give power to me going to wake the hell up and sort out my problem!!!
