Buying a plot in Devanahalli

Hello all, has anyone heard of BSNL postal and information technology housing society? Currently they are offering plots in Devanahalli at 1100 per sqft (Project name - Eco Nirvana). But the thing is that we wouldn’t get the plot now, as they are yet to complete a few formalities. Also we will need to make payment in instalments instead of making one time payment.

But at the same time I’m not sure if it’s actually managed by the real BSNL and also I couldn’t find much about it on the internet. It’ll be great if anyone can share their experience here
