Xperia V Auto-Reboot / Auto Turn-Off - And terrible HK Xperia Care service

Question

I am an owner of Xperia V (Black) and recently, the phone turns itself off automatically OR it reboots itself automatically whenever I use it for, say, around 15 minutes. It only happens when a SIM card is in the phone - it doesn't happen when, say, the SIM card is removed and I am only using WiFi to go on the internet. I use a 4G LTE card from PCCW Mobile in Hong Kong but in fact trying another 3G card there is the same issue.The most terrible thing is what I have so far experienced from the Hong Kong Xperia Care Centre in Mong Kok. I have brought my Xperia V for repair for already the third time and it has been the same issue which still persists! The first time (having waited for a week before the phone "allegedly" got repaired), the Xperia Care centre told me that they have changed the motherboard of the phone and things would be ok. But - no - just when I tested the phone before the Xperia Care guy, the phone turned itself off immediately when I was doing the Set Up procedure. Instead of having the phone back for further checking, the Xperia Care guy told me that it would be an issue with the PCCW Mobile SIM Card, and asked me to go to a PCCW shop to change for another SIM card. I did it, and it does NOT work and have to go back.I went back the second time the next day, and told the people that this is my second time of repairing the phone. The Xperia Care centre person then asked me whether I brought the "charger" of the phone so they can check the charger as well. I have no clue why this problem is related to the charger and why I am told to come back another time. I insisted to put down the phone for repair and in the end they accepted. Another week has passed, I got back the phone from Xperia Care centre. I was told they gave me a new battery for the phone. But, within 5 minutes of using the phone with my SIM card in (bearing in mind this is a new SIM card), the phone turned off AGAIN - despite having 9x% battery level!! It keeps turning off. I am so so so frustrated. I was stupid because I had already left the Xperia Care centre so wasn't able to show the guy the problem. But I just don't understand why the Xperia Care repair guy don't realise this problem - as long as they played with the phone for 5-10 minutes they would have discovered the problem.Now the phone is being repaired for the third time. I said that, given this phone seems to be unrepairable - I should be getting a new one instead of coming back for another 4th or 5th time!!! Unfortunately, the staff told me that this is impossible and they can only exchange parts for me.Sony, could you PLEASE make sure that this phone is getting well repaired before you return it to me??!! I am really sick of going to the repair centre for so many times and if this happens to again, I think I am going to swear I will never buy a Sony phone ever again. It's 3 weeks that I'm deprived of my Xperia phone to use!!
