HTC — Worst service center and are not knowledgeable to service

Address:

Tiruvallur, Tamil Nadu, 602001

I have given my phone htc one E8 for service on 18/12/15. the service center personells didnt call back for any updates and neither they took any steps for service.
i have been following them from 20, january, 2016, first of all the number is altime busy. and next after so much follows they said today morning that mobile is ready (26/2/16) but when i went for collecting the mobile they said it cannot be repaired and returned it.
this HTC company is a big fraud company, dont ever buy a htc phone.
they said its a liquid damage, when a company cant repair their own phone even when we pay for it, whats the use of running such a big company. i bought the phone for Rs.32000/-, and for service again they asked rs.7300/- which i was ready to pay. there cant b such company in market, its better to get some local company mobile, were they say use and throw and charge also within rs.10000/- for same features.
