Darlene Seitz ,Darlene Schreiber, Darlene Seitz writes false defamatory review and we haven't serviced her pool in years!!!! Anaheim California

Darlene Seitz posted a false defamatory review on our company.  We have told her she has the wrong company and yet she refuses to remove it.  Our company attorney will be contacting her.  We have not serviced her pool in years, her ex husband hired us in 2015, we later turned the account over to someone else and terminated service.  She purports we provided "terrible service, unreasonable to deal with.  Threatens to put line on my house for repair job that was awful and shoddy."   We do not have any record of a single complaint when we did provide pool cleaning, filter cleaning etc.  We don't threaten to put a line on anyone's house perhaps she's confused with the word LIEN.  Why would we have threatened a LIEN when she has no balance with us!??  She claims a "repair job was awful and shoddy".  We haven't performed repairs, she never called us years ago with any indication of dissatisfaction etc.  Just a nasty woman!  I see why D filed for divorce!  Now we have to waste our time and money to go after this wretched woman
