My phone's camera was not working properly so i submitted it at micromax service centre (Ms galore service noida sector 22) on 13/03/2016 . My phone was under warranty but they expired it by keeping my phone with them for more than fifteen days. They returned my phone on 31/03/2016. My phone's warranty expired on 20/03/2016 so they enjoyed its warranty period.No issue with that i submitted my phone with camera issue only but when i got it back its touch screen is inactive on some places. I went to get it repaired again now they say my phone is out of warranty. I think mistake i made is buying a micromax phone
