Actually, I can see that majority of forum threads are answered, and people, who even did not pay, because WP-Property is free plugin, satisfied.
WP-Property is very customizable plugin. I can do with it almost everything I want. I bought only Supermap, everything else I recieved for free. I can change what to display on map, one or few property types or properties with some attributes, I can filter them there. All I need was to press Check Updates on dashboard to make that premium feature work. It still works. Did you press on that button?
When did you ask for refund at first?
