Deeplinks are not working

Hi all,
My site:-https://coupons.antar.in/
At present i am struck with two problems
1) I created a deeplink for the coupon so when the user copy the coupon he should be redirected to the deeplinked page instead it is showing some other pages.
2) Once the page is redirected to some unknown page on the top of that page my logo is been shown on the black border with close button.Attached the screenshot of that.I dont want my logo to visible it should simply redirect to deeplinked page
Please help me to fix this.Thanks in advance
