left msg stating that I am listed as a point of contact of my illegit ex-wife

who I havent heard from in 18 years. States that some sort of litigation and complaint is going on with her and they need me to locate her and call them up at 866-284-3286. So shes using me as a POC or these people are trying to scam me. I could care less where that monster is at or doing, just leave me out of it.
