Xiaomi India — Not getting my redmi note 3 for 45 days from mi

My mobile is in the servicing center for over 45 days. I got the mobile in from flipkart. But after a few months i found a problem. The problem was that the mobile does not take charge. So we handed over the phone to the servicing center in parkstrret, kolkata, westbengal on 22nd august 2016 and they said that the motherboard was bad. But today is 6th of october and till now the mobile has not yet come. Its over 45 days i have been waiting. So i please request you to look into the problem and send the part as soon as possible
