bad service

On monday the 4th of january 2016 I upgraded on my contract that have had for longer then 10 years at vodacom. I upgraded to a sony z5, they told me the simswop would take sometime, which I agreed on. After getting home I switched on the phone to charge the battery while waiting for the simswop, eventually the phone got signal on Tuesday the 5 of January 2016, I started looking through the phone like anyone would do after rceiving a new phone. Which then It switched off, and didnt want to turn on again. I then phoned the person who helped me with the contract and he said I should bring the phone in and speak to gerhard he will be able to assist me, as he is the manager. It was only possible for me to take the phone back today 7 January 2016. As I stay 80km from town. When I went to the store to sort out the phone, I was told they have to send the phone away to check if it is a fault on their side only then they would be able to or fix it or give me a new phone, I asked for a loan phone as im traveling to joburg for the weekend. He said he couldnt help me. As I remember if the phone is brought back with a fault within 7 days they must be able to assist me.
