[Resolved]  Yu Televentures — My mobile hanset is not reparied and dilivered to me from last 1.5 month

I shreya haldia bought yu-yuphoria phone of yu from amazon online shopping. It is under warranty. After 6-7 months i was facing problem related to screen and speaker i have submitted the phone on 17.03.2016 to your bang lore service center who is authorized service center of yu. They have collected my phone stating that it will take time of 10 to 15 days to repair.
I called so many times to thier customer call center but every time i have received the same answer that your phone will be delivered in next seven days . I requested them that please transfer my call to some senior person but am not able to talk any authorized person . They are just harnessing us from last one month.

Now today is 29.04.2016, 1.5 month completed but not getting proper response from customer care and not from company...
