Lenovo — Improper service by lenovo accompained with poor response by customer care

Address:

Dehradun, Uttarakhand

I had purchased Lenovo flex 2-14 laptop with S/N-WB15105903 on 6th October 2014 . My laptop is not working since 1st august'15 and since then I had called Lenovo several times. After few days they replaced motherboard later their technician diagnosed fault and after few days replaced powerboard. Even then my laptop didn't power on so he ordered another part on 22nd august. Since then Lenovo has not provided any further service. Being a computer science engineering student, this major dealy in service resulted a heavy loss in my studies and a major delay in project submission which will be directly affecting my result. I also didn't got a proper response from customer care. One weak earlier they informed me to get serviced hardly by 12-sept'15 and today they informed me that I will surely get serviced by next week. I had conversation with Dasdagir(technical service associate). Kindly help me to get my laptop replaced as being a faulty piece and do take a strict action them.
