I had pathetic experience with this builder.
I booked an apartment in Krishna Mystiq. They promised to deliver by September 2015+ 6 months grace period.
Now in May 2016 also the project is far away from completion. They took 90% of the money and now they are not bothered about this project. They have very few workers(max 4-5 workers for project of 440 flats). When I asked security, they told Krishna is not paying to the workers. That is why they are leaving.
Would suggest to avoid this builder.
