My Rising Group investment: NRI nightmare from Dubai

Rising Group ka possession delay toh hadd ho gayi hai, especially for us NRIs. I'm based in Dubai, so it's impossible to follow up everyday. Invested in a 3BHK in Noida Extension, near the Aqua Line extension, thinking Jewar Airport connectivity will boost ROI. It's been almost 2.5 years past the RERA date now. Power of attorney se kaam chal raha hai, but it's so slow and frustrating. Builder naye-naye hidden charges add kar rahe hain, which wasn't in the original agreement. Is this common with other builders like Gaurs or ATS in Greater Noida too? How do you guys manage legal issues and find reliable property managers from abroad? Honestly not sure if this NRI investment was a good idea given these hassles.
