Acer India — delay more than told in replacing

Address:

Mohali, Punjab, 140603

I have an acer aspire 5 a515-51g and it ran into some problem and i called acer service centre. I have requested to acer service to replace my screen due to abnormal green or pink colour lines on it. They said that it would be replaced in 7 days. But its the 10th day now also it is not replaced and the case status is awaiting spares. Please help me out fast.
