Received a voicemail from 443 225 4257 saying that this was an independent process server by the name of Amy Sargentuay (sp).  She gave a case number in San Mateo County of cv 117164. She said she was going to serve court papers at my residence tomorrow between 3 and 5.  If not there to receive, she threatened to serve me at my workplace. If not received there, she was going to label it as a flat out refusal. She said I could call the people who were initiating the case but she did not provide their names.  About ten minutes later, my granddaughter (who is a college student) called me and said she was worried about me because this person had called her cell number about me and this "case."   I will be reporting this illegal activity to anyone that I believe can stop this person.
