[Resolved]  Lenovo — biased service charge rates

I have a lenovo laptop which is out of warranty. Its internet connectivity through wired LAN was not working so I submitted the laptop to IBM kolkata service centre at L&T Towers, Camac Street, Kolkata. They took a draft money of Rs. 1684/- which they told as non-refundable but at least I was assured that my laptop is in safe and able hands and soon enough I could get it working. Its to be mentioned here that I am a b.tech student of IIT Guwahati and I come from a humble background. The laptop was on an educational loan. After 3-4 days of their investigation they told me the cost of repairing is Rs. 21000 as the motherboard needs to be changed. I asked if some alternative repairs could be made or do they have any sugesstion about how to make the LAN working, they plainly said 'no' even after I told them that I am a mere student. I withdrew the laptop and started looking up at other shops where I found a simple hardware device costing only Rs. 350 and my problem was solved.
This is how IBM a.k.a lenovo in Indian market robbed me of Rs. 1684 without giving me any service. If they say that we can not possibly investigate for free, then I expect some sort of solution to my problem in return of my payment. They made the rules of advanced non-refundable servicing charge and by this means they are robbing the Indian markets.

We can not let them carry on like this... CAN WE ?
