Colive — Pathetic Customer Service - I want my deposit back

I have booked for a room in colive magnum. Initially, they were calling me continously. After I made the booking, I did not get any single call reagarding the update. Worst bunch of service providers I have ever met. I called the property manager (Gautham) twice and he has declined my call and has not called me back. An executive by the name of Supriya was very rude and impolite in her behaviour. I want my refund back.
