SHOCKING SERVICE

Nexus 5 -June 2015. the day it arrived I could feel the battery was loose inside and the phone kept turning itself off. I was told by the company to open the back and glue the battery in - apparently they thought this would not void my warranty despite the manual CLEARLY stating it would. I sent the phone back and it was returned 3 weeks later and I went overseas for two months. within 2 days of having it the phone was turning itself off continuously and not even loading to the menu, this drained the battery, no one could hear me during calls despite good signal and full volume and after charging it the screen became overexposed (unsure how to state it). I sent it back in september when i returned. i had to email them every 1 to 2 weeks to see if anything was happening as NO ONE from the company INITIATED communication. I have been told now that the phone is in transit to the supplier - its been in transit for 6 weeks. I was informed that I cannot get a refund or replacement as they repaired the battery - however this was not my fault. They sent me someone elses phone accidentally and I returned it 4days later, told I will receive mine within 2days I didnt- its in transit2 supplier
