I'm Andrew, a Community Manager here in Trulia Voices, and so can speak on Trulia's behalf.
The best way to sort this out is for me to take it directly to Customer Service. Can you please send me the link to your house's page on Trulia? Once I have that, I can get it taken care of.
Also, are you working with an agent to sell your home, or are you listing your house on Trulia yourself? I ask because currently, Trulia does not allow home owners to list their own homes on our site.
Thanks, and looking forward to hear back from you,
