I have had the same thing on a site of ours for a long time, maybe 2 years.
They say our site ranks at #5 for its main keyword when in fact it is nowhere to be found.
The site **was** on the first page then got hit with one of their so called UN-natural link warnings. We basically told them to piss of as Bing loves the site and we are building sites for **people** and not going to alter anything to try to please some search engine as per their guidelines.
What it looks like is their wonderful tools show the rankings without penalties, they are basically cloaking, showing the webmaster one thing and real visitors something else.
