Lenovo — Yoga/ i am complaining about no resolution to my laptop issues despite being in warranty

I bought the lenovo yoga in oct2014. I wanted my warranty extended as i was not in country aimce then till 2016 feb. My warranty was extended on payment.
There are so many natural issues in laptop-
1. One usb port is not insertable
2. Other usb port is loose contact
3. Charging not happening recently.
4. Hash+c not working.

Service centre people conveniwntlty rejected.Customer care making fool o[censored]s by first asking us to make a video and then saying the same thing.

How can you conveniently say things are under adp. My warranty extended was exactly the same as told to me.
This is sheer cheating.
Such a costly laptop and such awful service.

I need my money back. Replace my laptop!
