LG Electronics — Nexus 5 Not getting Started only Google Flashing up again and again

Address:

Ranchi, Jharkhand

I purchased my Nexus 5 in Jan 2014 and phone was working fine till November start and suddenly problem started up with it which was phone not getting started and only google flashing up again and again.I visited the RANCHI service centre and was told that mother board will be replaced as the phone was in warranty. After few days when i didnt get any response from i went to service centre to collect the phone, and was said that mother board is fine for now and only software has been re installed and the phone wont give the same problem again. Bringing into notice at the time of 4.4 Kitkat i got the phone with 4.0 software. The phone was working fine for few days and then sometimes it starts getting reboot on its own. On 13th Feb when i was out of station the same problem started again with only google flashing up again and again and phone not getting started. After coming back to hometown on 18th feb i visited the service centre again and then i was said that mother board needs to be changed and i need to pay 9k for that as warranty expires few days back, Here my question arises to LG service that isnt there a big question mark on the service you are providing? and secondly when the same problem occurred in Nov and phone was in warranty why was the mother board not changed that time even when i was told that they will be doing that.Now when the warranty expires you ask me to get the mother board changed.This a pure case of cheating a customer which was never expected out of LG. My phone is submitted to your service centre since a week and i didnt get any response yet regarding its repair under warranty. I need the phone to be repaired under warranty as its LG's fault that you didnt change the mother board when the same problem was occurring at warranty time. I need the department to take the necessary actions as soon as possible.
