F-15/1 plot 500 yards or a 30x60 or 35x70 in g-14

Dear experts, i need your advise, i have a 500 yard plot in f-15/1 which i bought 10 years before. I still have not received possession of the plot (number is 276-278) although there is a street already in front of my plot but i cannot get possession because i have been told by the society management which is probably the most corrupt management on earth that it will be given soon. I am not sure if i can get possession or not because i can see a boundary wall at the back side of my plot which covers the last 20-25 feet. I need advise from those guys who have good knowledge about the society if they can make it happen in a year or so or i should sell this plot and look for another alternate i need an advise if g-14, 1,2 or 3 size 30x60 or 35x70 is better option or they will also not give possession like jkhs. I have no idea why government and these societies sell those plots to public for which they do not have rights to sell. Please advise the best you can - an overseas pakistani.

Sir it is good if u can switch to G-14.1.2.3 or E-12 Even if not developed will give u good return and these are proper cda sectors
