How do I get Zillow.com to make an important correction in the price I paid for my home in 1990?

Zillow.com is listing the "last sold" price for my home at just over $22,000, when in actuality the price paid for this home new was $195,000.00.  I think the error arises out of the fact that we obtained a swing loan because our old home had not sold yet, so our loan included additional money to allow us to pay two mortgages until our old home sold.  After selling our old house, we then paid off that swing loan, which is undoubtedly accounts for the $22,000+ figure you saw.  However this error could be devastating to me in trying to resell my house, and I demand that you correct your error.  You need only recheck the County Recorder's office to verify the information I just gave you.
