Obvious scam attempt. Phone, fax, text or email is not a legally valid way of "serving" you. If you were going to be served, you would have received lots of mail. Then a visit from a process server - who does not call you ahead of time (or text)!

My elderly grandmother received call from Phone # 323 487 2744 person asked for me. I do not live there. They
called her by her first name. Very forceful regarding impending court hearing, threatning my job, if I do not appear for the hearing. I have in the past been the target of scams related to IRS and other things. How come I seem to get targeted frequently I have no idea. I wish I knew how to stop it.
My ex husband received a call from 323-487-2744 looking for me to serve legal documents. Said I had to call within 2 hours. I called but was put into voicemail. Gave my # but did not receive a call back. Did a search and found nothing for TPS.
