Groupon India / Nearbuy — Company is not allowing me to take my amount

Address:

Whitefield, Global axis , Bangalore

I have completed all the tasks assigned even though it's beyond my limit.(I invested only for 3K but the company took to 7 lakhs).Now the tax paid, and big channel amount paid and also withdrawal handling fee also paid.But again they are asking to change the bank account and again asking me to pay for big channel.Its highly impossible.
Request you to get my funds principal amount which I invested back (I don't even want interest).
