Planning to invest in Sandeep Sqaure.Need advice

We have almost finalized on a 3 BHK here but not going ahead. The builder is not ready to meet up for any discussion. Come on! ..We are investing almost a Cr and we cant even meet the person in charge.. Every time we get to speak to only the sellers over there who are not decision makers. If this is the treatment you get before investing itself, think what will be out fate after payment. Also, I am told the project is already delayed and they are committing possession by dec. But with the progress I have seen, I don't expect this to complete at least for the next 7-8months. They tell you the sq feet rate as 4700 and come down a bit but they take all the money in the name of parking , amenities etc. Net net you will be paying minimum 5000 per sq.ft at which you can get a must better builder apartment.
