Inquiry about state life insurance employees housing scheme

Hi,

I have a 10 marla plot in state life islamabad (near new airport).

I would like to know about the current on-ground details. My father purchased this plot in 2005. More than 13 years and still there is no development. Recently, i received a call from their office to pay the remaining development charges, but i am skeptical about their claims, as i don't see any progress and not even expecting that in near future.
