Does any one have an idea of this new 'Corporate Agreement' they created?

Q: I have a flat in Tierra cluster. Recently, my 'Customer Executive' contacted me saying that they have entered into corporate agreements with banks such as SBI, HDFC and others and convinced the banks to release payments. Even though they have permissions only till 4-5 floors, they are demanding money from people who have booked on higher floor. I wonder how they can do this? How can banks, sanction loans in the first place when they knew that permissions were not complete? And how can they disburse money through some private agreements? This seems to me like banks and the builder are in cahoots and we, ordinary flat owners will be skimmed. Does anyone have a different view? What can be done in this situation?
