Projects of this magnitude and with such high legal complications, it does come under the Government's responsibility to regulate these bodies and make sure they are not committing fraud, it's not some kid selling you items on the street, now is it? It's a gigantic company selling you properties on land, with the approval of the Government, or what do you think happened? They just turned up one day, police and rangers saw them and thought that 'lets help them out!' and helped them acquire land, and they just began selling? Are you really that thick?
But that aside, the contract provided by Bahria to the investors and property buyers, under law, would not be considered a scam per say because of several reasons.
One, they are a registered company. Two, they cannot sell or acquire land without approval of Government, which did so by the approval of the Sindh Government, the Police and Rangers on directions of Provincial Government assisted them in attaining the land. Three, they are actually delivering on their promise, they are not leaving their promise out, to scam is to promise something but not deliver on that.
Now, I know you lack the thinking capacity, but it's fine. There's something in the law that goes by the term of Consumer Rights, you should read up on it a bit, it will clear it a bit more for you.

These judges are here for only fame, not justice, unfortunately.
