Airtel — redirecting to oneairtel

I just recharged my phone which a new data pack and as soon as i did it most of the sites are not opening. They get redirected to http://one.airtel.in/rcconf as a result i have not been able to use some coupons, and i am not able to browse through most useful sites. Please give a solution for this. I am losing on money because of their redirecting and i tried to reset apns and cleared my caches in all the browsers i use, nothing helped. I contacted 198 but they told me they don't deal with this issue. It's really harassing and i dont know where to go and how to deal with this. Please provide a solution soon.
