Apple India — Unresponsive touch screen (Degrading value of apple in India)

I purchased the iphone 6 (32gb) variant on 1st april and the touchscreen went unresponsive on 8th of the same month.
Is this correct??
As this was my first iphone i was so much happy and wished to buy a macbook air but i would have to think once again.
Today on 10th i went to the authorised service centre and they said it would take around a week to know if my phone would be replaced or be repaired.
If iphone needs a repair within 10 days of purchase and not replaced i m very sorry but this doesn't keep a good impression on the consumer part too.
the other thing is when i walked in the service centre i saw many other cases(approx 5 to 6) who had iphone 6 and had different sort of problems.
If the model is so problematic or if there may be a lott which would have some problems you guys really need to check.
Ps. never gonna buy apple products; China products are more trustworthy
