Sony and its failing Xperia M5 Flagship Device

I took out a Sony Xperia M5 with CellC on Friday (11 Dec 2015) and on Sunday (13 Dec 2015) i had to take it back to the store because of a constant power problem where the phone will switch off by itself and then need a charger connected before it switches on again. I then had to wait a whole week (without a loan unit) for the replacement. I got the replacement on 18 Dec 2015 and after 10days the phone started doing the same thing. For that 10days the battery life was the worse i have experienced. I took the phone back on 4 Jan 2016 and till today i am still awaiting feedback.<br> <br> I hereby want Sony Mobile ZA to honour the terms of the CPA and give me a replacement unit with the same specs as the M5, but not that unit again. I took the phone based on specs not pricing.
