Investors Clinic — Never buy property from Investor Clinic, they are frauds and cheaters

Around two year back I had bought a flat through IC at Kresent Homes, Noida Expressway. At the time of booking they has issued us a credit note that said the would refund us a part of the brokerage fee once we've made 30% payments. It's been a year now since we've made 40% payments and even after running behind them they just refuse to refund us back the amount even after we've submitted all the documents.
