Good luck. I had a horrible time trying to get MLSsupport to correct information that they (or their subcontractor) carelessly entered incorrectly. I finally gave up on much of it. What I was able to get corrected was fixed by figuring out to whom they had subcontracted the listing, and contacting that subcontractor directly. Sorry if this is too late to help -- I know that misinformation at the beginning of your listing time-period causes a lot more damage than one can easily quantify, and the damage cannot be undone.
