Contract Samsung Phone not working - wait 3 weeks

My neighbour (no vehicle no drivers license) which is deaf and have a dyslexic son renewed her contract on Wednesday 11/11/2015. She received a new Samsung (with a new SIM).<br> The phone did not work - so she took it back on Wednesday.<br> The assisted took the battery out and bashed it on the desk and when placed back it looked ok.<br> It stopped working soon afterwards.<br> The phone was returned today (Friday). He bashed it, and the even swapped batteries. It did not work.<br> She is on a contract. SO now, no phone and told it will take 3 weeks for repair.<br> The manager told us that this is procedure -and even if he call his boss it will not make a difference.<br> She now can not even use her old phone - however Vodacom got the contract and she will be paying for the new useless phone and no telecommunications to the world.<br> My cell number is *** - since nobody would be able to contact her!
