HTC India — Mobile repairing

I have purchase htc mobile me9 on 25th oct, 2015 due to battery over heat and charging issue i have given my mobile for repair at thane service center ie tvs elec ltd. At eternity mall on 1st june, 2016 and after continues follow up i have been inform that my hand set mother board is require to replace and same will take 8 to 10 days there after on 22nd, june, 2016 i ahve received sms staing my htc device is ready but to take delivry when i went to service center they said more 3/4 days required which is very disappointing and till today i ave not received any call from service center for mobile repair status hence look in to the matter and or replace my hand set since it is warranty period.
