I still get a check from them every month, but I would agree that there are serious problems. I still have reservations showing as pending since January 2005... which equals around $4850.00 they still owe me. I was only using Lodging.com because TravelNow/IAN was not doing ichotels ( Holiday Inn, InterContinental, etc...). Last year they blamed it on a glitch, and I received a $2300.00 check about a year after the fact... I'm guessing the same will hold true with this $4850 in question.
After dealing with the sillyness, I moved on from lodging.com back in October of last year... was offered a better way to deal with ICH directly, and have been paid a higher % on-time, every month since.
Personally, I'd drop lodging.com like a hot potato.
