sony experia m4 aqua

this is my story<br> <br> i upgraded on my contract the 1st of july 2015.<br> after recieving the phone i had to return it 2 days later because the camera didnt work. it was sent to johannesburg to be repaired after my understanding was that i was suppose to recieve a new phone because it was returned within 7 days of recieving the phone.<br> <br> after 3 weeks i got the phone back and was working perfectly but a week later just stopped working again and was sent to johannesburg again. it has been 2 weeks again and havent heard anything from vodacom in regards to what is happening with the phone.<br> <br> the job number regarding the phone is ***4.<br> if this doesnt resolve my problem my next step will be the consumer act and vodacom ombudsman
