Faulty Cell Phone

Good day<br> <br> My fairly new cell phone which I got last November has not been working majority of this year. <br> <br> I have taken this phone in twice because I never have signal - I cannot register on a network. The phone only works (received messages) when I am connected to Wi-Fi. I cannot make phone calls or receive calls at all unless I restart the phone every 5min. <br> <br> I also asked if my camera could be seen too as it takes about 20seconds to take a picture. Well, the camera is still not working properly. By the time the picture decides to capture, the moment is over. <br> <br> I just got my phone back for the second time literally two days ago and I am still having the same problem. Their is definitely something wrong with this phone and sending it away for another month will not make a difference. <br> <br> I am requesting that someone from Vodacom helps me out with this situation - I do not want to send it in again for another 'repair' I would like a new (non-faulty) cell phone. <br> <br> Regards<br> Monica
