Extremely Poor Repair

I had an issue with the lens of my brand new xperia Z3 compact after only 4 weeks of having the phone. I took it to my vodacom repair shop near the absa cricket stadium in Durban and they had to send the phone to JHB for 7-10 working days! The phone was also wiped. I also received a entry level free loan. All the standard practice but still frustrating! I got the phone back and was told the entire back of the phone was replaced.<br> <br> I was trying to take a photo now,removed my protective cover & felt that the entire back of the phone is loose! So whoever repaired it has either broken clips, or not *****ed things back properly etc.! This phone is less than 4 months old! There is not one scratch on it, it is in perfect condition and now I have to go through the whole rigmarol of sending it in for repair again! After the so called qualified JHB repair guys got their hands on it. I have lost all confidents in the quality of the repair when the phone had a faulty lens in the first place, within a MONTH! As far as I am concerned they should have replaced the unit in the first place. Now I need to send my phone away and get it wiped again! I would like a new unit please. This is un-acceptable
