[Resolved]  Airtel — http://one.airtel.in/rcconf redirect issue

Hi! So i received a message from airtel that they are providing me free 10 GB data on a 4G sim+ 4G handset by calling on their promotional number. As soon as i called, i received 10 GB free data and here where the problem begins. I cannot open certain websites on google chrome like ( facebook, etc.) as it redirects me on this link http://one.airtel.in/rcconf again and again. Tried clearing browsing history and APN numbers. Also i cannot open any game downloaded from play store. What kind of joke is this Airtel playing? Why even bother to give free data when you can't use it freely as you are redirected to their irritating webpage. Please provide me a solution as soon as possible.
