I just got this call too. My heart skipped a beat. Thank goodness I see that I am not the only one and that this is probably just a scam. I would think if a restraining order were placed against me I would have had to have it given to me directly? I'm not sure. Never had one. But I will not worry about it.
I received a call from this number on my work voicemail, telling me I had 4 hours to contact them or they would be contacting my employer, filing something in court, and so on. Not once did the person state their name or who they represented, or why I was being threatened.
