Xiaomi India — Xiaomi redmi note 3 - Service Issue

Address:

Pune, Maharashtra, 412101

On 21st May 2016, I have made complain in Pune, Shivaji nagar xiaomi sercice station and received my phone on 7th June 2016 after multiple follow-up and escalations. Then I go for online service i.e. PickMI service from xiaomi as phone was not functioning well and found multiple issues after it's repaired.
Since 3 months, my phone is still under repair and today(2nd sept 2016) they said, there is tempered damage within the phone and it will not be repaired even my phone is under warranty.
I asked them the reason how that damaged happened, it is from last service, transportation or from your side. Because, when i gave the phone, it was in working condition. Now, it seems to be dead.
But, they didn't gave any answered till date only they are saying that, phone will be returned back if you are not confirming on bill payment.
currently, I am helpless because, they xiaomi phone and email service not connected and i am not getting proper response in timely manner. And no one is ready to give answer on my queries and I don't get any resolution since 3 months.
Requesting you to look into it and resolve this problem. Since 3 months I got multiple request and incident # because, they change that number in every week without solving that issue. so, I am sending you latest details for your reference.
