Bad Service and no feedback

I have app**** for a new contract over the phone with Vodacom.<br> Eventually I have received my device but with a micro sim. I needed a nano sim. So I phoned Vodacom and requested the nano sim, they delivered. I then used the micro sim on another number (doing a sim swap from a data contract) in another devise. When phoning Vodacom to activate the nano sim no one said it can't be done. \it will be activated in 48 hours". <br> <br> Then I phoned back more than a week after and they tell me they can't activate the sim on a new number they need to activate it to the number that is ALREADY another CONTRACT on someone else's name on Vodacom??? How can you just use the same number on two different contracts? Does not make sense. They said they will phone me back but I have to phone back every time.<br> """
