Dell India — The patch of the screen had been plucked off

I bought my dell laptop on 3rd of April and within a one month the patch of the screen had been plucked off. On 20th May the side of the screen was bulged out and please mark my word it was neither mishandle nor fallen down from anywhere. Till 22nd the part of the screen pilled off and I cannot open my laptop. I have shown it to the shop from were I purchased it and they said it was a manufacturing defect.

Please help as it is still in the warranty period.
