Horrible agency and very unprofessional. They listed a property which was not available for market and organized inspections for that. I submit my application and waited 10 days and missed few other properties and finaly after chasing them 4-5 time they told me property has some dispute and will not be available for another 4 months !!!
If that was issue should it be listed at first place ?
