Phone still broken

In the beginning of the month, I complained about my phone which was handed back broken to me by the Vodacom Repair Centre outside Somerset Mall.<br> <br> After a long battle, they replaced my screen. Two days later the screen started lifting again. I then booked the phone with the store manager who sent the phone to Vodacom's Advanced Repair Centre in Johannesburg. <br> <br> The phone was sent away on the 20th of Jan and I received it back the 27th, a week later.<br> <br> Having not had my phone for a week, I received it back from Vodacom with the screen STILL lifting! <br> <br> This is totally unacceptable! I've taken it back three times to have the screen pressed back, then it was replaced, then it was sent to Johannesburg, and the device is still broken!<br> <br> What must I do? Please tell me? I am fed up with the pathetic service I'm receiving! This is still a fairly new device. Why can't it be replaced?! I've been to the store almost every week this month!<br> <br> I am fed up of using my time and remaining phone-less for a recurring problem which Vodacom is unable to solve! <br> <br> I am disappointed in the lack of concern and care that Vodacom has shown me! I'm still sitting with a broken phone!
