IMT Desert View

About 2 weeks I moved out of my apartment that I lived in for 12 Months. Over the course of these 12 Months, I was very careful that I did not cause too much damage to the apartment. While returning the key, I requested for appointment for walk through. I was told that walk through is not required and I will be charged only for major damage. Today I got a mail asking to pay 831.18 for the damages caused (Split up given below). They are telling that its my duty to schedule walk through and if it was done its not their fault. More over the staff who was working with me during returning of key is telling that I never requested for walk through.
Manager was not ready for the discussion and kept saying "Sorry, we cannot change anything on this damage". When brought up issue about staff , both staff and manager started moving in and were not discussing with me any more.
