Signed up for Loopnet using a corporate card that had a lot of advertising on it. Listing was ineffective so after a number of months I cancelled. Two months later I got a call on the listing so I realized it did not cancel, I cancelled again on the site, followed by a phone call and an email. This time the listing came down but they kept charging my corporate card, which is mixed with lots of other similar advertising (i.e., for almost another year before I caught it. I know, I should have caught it but when I called them they said that I sent my cancellation to an automated email account that they don't monitor and there was nothing they could do to help. If you would like to join in a class action lawsuit against Loopnet/Costar, it's clear from this review board that they do this frequently and intentionally.
