There was display problem in Redmi 3s. I handover mobile to service centre on September 2, 2017 they promised to give mobile with new display on or before 7 days! But it's been 11 days still they are saying it may take 3weeks more. Service centre guy says there is no stock in service centre! Company is not providing parts on time!! Who is responsible for this big delay!!? I need answer for such an irresponsibility.
