My M3M Sector 150 possession nightmare

Since 2021, I've been waiting for my M3M project in Sector 150. The promised possession date was last year, now it's indefinitely delayed. RERA filings seem like a joke sometimes, honestly. I'm paying EMI for an under-construction flat plus rent elsewhere, which is just draining. This wasn't the calculated risk I signed up for. Has anyone else faced such significant delays with M3M or other builders in Noida? What recourse did you take?
