I have been worked with Krishna group from last 5 years..
On the basis of quality and qunatity of work, i can say I am working with right people and right place. They completed project within timeline given at lowest price if you compare with others.
Never pay the money to the vendors. We have done the interiors of the office and the owner has not cleared the bill. Even the Mandir is donated by us to them. My suggestion if you can't afford you should not renovate the office. How you can sit and work as you know all the facility you are enjoying is of someone's else's hard-earned money. Big Shame. I believe in Karma and it hits back.
