Rather have your house on the market then making selling a priority

This is ridiculous that we are interested in a property and would like to view and sign offer to purchases, i have an agent selling my current residence and want to keep with her for purchasing a new property, but you unwilling to let us view as you dont want to work with other agents. For future we know now not to list with you as you will rather let a property stay on the market then making selling your priority. Just bad service.
