JMD Property Bazaar: Anyone else facing possession delays?

I'm seriously regretting booking with JMD Property Bazaar. Currently in a 2BHK in Sector 15, thinking of upgrading to a 3BHK. But their promises are just hollow. Possession was supposed to be last year. Abhi tak toh kuch bhi nahi hua. EMI bhi jaa rahi hai, rent bhi. Is it even worth fighting them? Already have a home loan, can't afford another one. Anyone else facing similar delays with them? Kya karein?
