Identified himself as being with my timeshare company calling to get me money back for missed years and back maintenance fees. I'm paid ahead and have never missed a year at the resort. He was not aware that my property never closed during the pandemic and didn't identify what my property was or where he was calling from. When I terminated the call for being suspicious, he called me back to yell at me for "not listening." And said he would put that I am "disgruntled" in "my file."
