Consumer Redressal

I purchased a mini sewing machine worth Rs.1950 online from shoping.in website on Aug12,2014(I booked on 31/07/2014 and I got deliverd on 12/08/2014 thru Bluedart corier)but the machine deliverd to me is not that machine which they are showing on their website.Moreover they told over phone that they are providing 100 spools of thread for free,a free gift voucher of Rs.1000,nd also a list of service centres in our area where all these assurances r not fulfilld. So I want to send back the product as they are having 30 day money back policy as I did not touch the machine at all till now.But when I am trying to contact them over phone reg this,they r not at all lifting the phone or by chance if they lift the phone means they are giving evasive replies,talking in insulting manner and disconnecting the phone.I want to teach them a lesson with your help and so that they should never cheat one more customer like me and I want my money back. Let them take back their product.Pls help me pls
