<prompt> Human: Sold a house in pa this past summer that was in an estate. We have since closed the estate settled all the debts etc. etc. Suddenly I get an email stating that the title settlement company made an error in calculating something and that we owe 2300 bucks by Saturday. the person hasnt sent us anything in the mail up to this point and they want us to call them and talk about it. When we were settling the house this person was a dick and Im of half mind to not respond and just let it go. Ive moved out of state and really dont want to have to deal with this anymore. What should I do?  <response>: tell him your attorney advises you to only deal by certified mail
