HTC — Mobile display gone in 45 days

Address:

Coimbatore, Tamil Nadu

I bought HTC one M8 03rd Oct 2014 for 43, 000/- it was good for some time, last month from 10th Nov 2014 it started showing display problems. i have given it to HTC service center now. I am really saddened by this incident i never thought this phone would give some problems, feeling disappointed buying this phone. service center guys told me phone will get it repaired by 2weeks of time but i still have not recieved any conformation msg from the service center. when i called last week to know the status the customer executive told me it will get delayed as the item to be replaced is not in stock. this is not the approach i am expecting from this company. kindly help!
