Ask HN: What to do when a leading Telecom operator neglects T&C?

Recently I found out, when I access facebook login page through my GrameenPhone mobile network, I see-

"By proceeding you also agree to Grameenphone Terms and Conditions."

However, that link took me to the home page of their website, and I found no Terms and Conditions regarding accessing Facebook through their network in that page. You will find the screenshots at http://imgur.com/gallery/weMq8

FYI, GrameenPhone is a part of Telenor Group, and has 56 million active subscribers in Bangladesh.

How is it possible for a multinational multibillion dollar company to do such thing? It clearly is a negligence and disrespect to the whole concept of mutual Agreement. They can harass anyone by putting anything there in time. How shall we take step to make them listen and put the original Terms and conditions there?
