Al Jalil 5 (7) year plan update

hi there, I invested in al Jalil almost 5 years ago but they added double development price charges and made extended the plan for 2-3 more years.

will they ever give the possession? should I sell the land or hold? my money has been stuck with them for past 6 years and no return infact, no plot or possession given yet but they launched Alnoor and so many people trust the developers, they invested lots of money there too.
