I have been trying to post a property and used 6-8 sites.
I have not had issues with any other site but Magic bricks is unique in respect to make you pay by denying your listing.
If they advertise free posting then it should be free, they keep on rejecting till you have no way out.
The images that I uploaded, all 5-6 sited took it without any issues, but Magic bricks kept on rejecting.
