Website with fake offers. Review on eBay India Pvt Ltd

EBay is the international online e-commerce shopping website. Recently eBay announced the Toshiba gb pending for just 99rupees. They were conducted the eBay contest sale. They were collected the mobile numbers from us and sent the coupon on 28th September 2016. I also participated in the eBay flash sale. I updated my mobile number in the eBay Toshiba pending contest. Almost 28th September 2016 goes to complete. But I did I not received my coupon from eBay. They did I not sent any coupon for me. Actual price of the pendrive is 336rupees. At the payment page we need to apply the coupon which was sent by the eBay. .The value of the coupon is worth 267rupees.But I did I not received any coupon from eBay. I understood that there is no contest. They only done the business only. No special offers are there in eBay. Even 100rupees off coupon also not working with the new eBay account. I tried for a other pendruive as new user by applying 100rupees Off coupon. It is showing that enter a valid coupon. The eBay is promoting the faker offers and coupons. I don't want to trust easy.
