Your agent/Realtor should be able to help you get this corrected. If they don't respond within a reasonable amount of time, you might try calling their Broker. I wish you luck!
From that page, this is ABOR's direct contact info for this stuff:
To report MLS violations, contact ABoR's content quality representatives:
Hours: 9 a.m. to 5 p.m., Monday through Friday
It is not hard to get corrected. Is your (or this) property listed by a professional REALTOR?
It is possible that the ML# & Price are wrong for the current listing but actually refer to an old listing. This is one of the downsides of sites like Trulia, old & out dated information languishes for weels often and years sometimes.
