Morestore — Not getting warranty on purchased laptop

Address:

New Delhi, Delhi

I manoj talreja bought a Lenovo laptop from more mega store in kirti nagar.
but after few days of purchasing, I found that laptop is already registered on companies employee name (tarun) from 2 years .
which means I bought a second hand laptop from that store .
when I told all these thimgs to mr. khan & mr. tarun( employee in more mega store ) they denied that's its second hand & promised me to give 2 years warranty from Lenovo.
but after making many calls to them, they always promise me that it will get done in few days
and at last after 4 months they refuse to give me warranty & asked me to settle this & take 3000 rs. from us .
so please tell me what should I do further.
please contact me my no. is [protected]
