Airtel — poor internet connection

I am a airtel 4g user and since few days the network had gone so bad that it can't even load a simple watsapp image. The problem had also seemed earlier. Kindly give some interest on my problem because i can't even open my facebook account. The internet connection had gone so bad that even if a search something on google it will not load. Please fix it soon or airtel will loose a customer. This is not the first time i am facing problems with airtel. You people claim that it is the fastest network in india (Lol).
