A couple of years back I purchased a few flats in an under construction property in Dahisar from a reputed builder. This was an under construction property that I invested in. At the time the initial down payment was made, we were given receipts for the same and we were told that the flats we'd booked then (the reciept bears details about the flat numbers that were booked) were reserved for us. Since then we've paid close to 20% of the cost as requested, however an agreement has still not been drafted by this builder and each time we ask about it, we're told that the same will be done soon.
Earlier this year there was a change in plans for the buildings and for 2 of the flats that I booked i was pushed to a higher floor. In spite of the fact that the change was from their end and not a request from me, I was asked to pay floor rise. My question is - How legal is this and can i fight back since there is no agreement yet and I was not given a choice in this respect? I am basically stuck with a flat at a higher floor that is not something I wanted and I am being made to pay excess for this now.
Seeking some expert advice with respect to my problem.
