Negligence of customers preference

Location/place: Delhi

Name of company/service: Investors clinic

I was looking for a flat and booked a flat in Logix- Blossom County through Investors clinic and tell them my preference, but when I received allotment letter it shows different floor that I was looking for, so I call them but they do not talk me properly and do not give me response. I was not interested in any other floor. So I regularly tried to talk with then but it was all in vain. They cheated me in this way and it was the worst experience of my entire life.
