Vastu Vihar — they are giving us the incorrect flat

Address:

Deoghar, Jharkhand

Agreement says i have 2 flat north west and north east.
But they have done incorrect numbering and are trying to give me 2 flats south west and south east.
They are doing so as we assume because they are getting more money now.
They have done numbering as per their own convenience.
We assume they have edited the documents of other customer to give them the benefits.
We are in the need of the desperate help.
