Amazon — Htc/complaining about handset

Address:	143001
Website:	www.amazon.in

Sir,
I purchased htc mobile phone (model no. htc desire 526 g plus/glossy black 16gb/dual sim) having imei no. [protected] on 12/11/2015.

Roundly after 3 months o[censored]se, it started causing a speaker-mike problem for which i registered a complained to htc service centre (amritsar, punjab branch of ganpati towers) on 01/04/2016. when i could not get any response from the service provider even after 20-25 days of registering the complaint, i myself called them and heard a disaster response from them which was:-

“ your phone is out of warranty and some parts of it has been changed by someone else”.

Now, my question is ‘how is this possible’? if warranty period in every normal case is 1 year, how it can get over within 4 months?
Second and the most important thing is

“how can the parts of phone get changed, when i am handing over the newly purchased phone to htc service centre”?

After that conversation i’m continuously getting here-there answers from officials and i’ve given my un-repaired phone back.


Regards,
Harmeet singh
