Snapdeal — Sent wrong product and now refusing to replace/return

Address:	New Delhi, Delhi
Website:	Snapdeal.com

I have ordered Lenovo G50-80-80E501LRIN laptop priced 42389 Rs (Order number [protected]) by COD on 10 september but they delivered tummy trimmer. I live in almora but they didn't support here So I ordered it in my relative resident at haldwani. Because the box was sealed so they taked the delivery but when my sister opened it, there was a tummy trimmer. On next day I asked for replacement and contacted snapdeal. They assured me that they replaced it. I sent them photos related the product. But they replied, We have investigated the matter and found that we sent the laptop. So we can't help you on this matter. What should I do now? They are fraud & sent me some cheap trimmer.
