Lenovo — I am complaining about lenovo laptop ideapad 310

Address:

Mumbai City, Maharashtra, 400007

I purchased a lenovo laptop from croma in october 2016. Product name lenovo ideapad 310 serial no pf0nu6ls. Soon after the purchase within 6 months its software got curroupt and i lost all my important data it was not my fault at all but i compromised and let go it. Then recently i started facing a keybord issue in my laptop and took my laptop to the service center. Firstly they did not have power adaptor and hence took my adapter to service my laptop. Secondly they said that they will get the issue done within 2 days. The next day i get a email saying that the part is not available and i will have to wait for 1 month (Written in the email by them). They just sent me this email without providing and solution for the problem. I spoke to the service center people they asked me to talk to the lenovo customer care for further solution and they cannot do anything on their end.
I then called customer care for the problem to be solved they transfered my call to their head named "jyothsna vas" email id "[protected]@lenovo.com" i explained them that the part is not available is your problem i am in urgent need of laptop i need to do my projects and submit it. Then she said that she will update me within 1 hr. Then after 2 3 hrs i got a mail from her that they cannot reach me due to a problem and hence send a mail that there is no update from their part team on the availability of the part and asked me to bear with them. Then there was no update from their end. When i send and email to update me on my issue i got an automated response saying "i am on leave hence there will be delay in response" this line is cut pasted from email. If you were on leave why did u attend my problem. They just fooled my they stretched the issue thinking that the customer will forget and avoided me instead of solving my issue. I again called the customer care today around 11 30 12 and they say that they are not available. I called on[protected]. I then approached the service center they said that u can take your laptop and purchase an external keyboard thats comes for around 200 rupees and do you important or urgent work and when the part is available then we will replace it for you inspite of my product being in the warranty i have to pay to get my work done.
Can't the company proved me with an external keyboard at their cost as an alternative if the consumer is ready to corporate.
Its not even 1 year that this product for launched and the parts are not available.
Product costing 45000 rupees giving problem in less then 1 year and always the customer (I) have faced the consequences (Loss of data).
They have raised their hands asking me to wait for 1 month
I am a student of iai i am apearing for ct9 exam and i need to complete my assignment and submit it before 4th of november also my study material is on the laptop how do i complete my work.

My job sheet so number is "[protected]" provided my service center which will give you all the information.

I request you to help me out with my problem and of possible to replace my laptop as its less then a year ther are 2 faults and such service after my warranty period if there is some issues then i wil have to bare more costs again.

Thank you
