I bought new lenovo zuk z1 phone on june 2, 2016. It got defect within 1 month on july 2, 2016. It has mother board problem. So i called customer care many times and i had to give this to lenovo service center and now they doesn't have mother board part and every time when i called them they said it will take 10-15 days. I bought this phone for myself not for the company. Because they have my phone more than me.

So please help me in this by providing my money back in my account or replace my phone.
