Received a voicemail from a man with an accent being very rude about disregarding the call and said if I don't call him back, an attorney will get involved and good luck.
My mom just received the same call as Zach did, it was a person leaving a message and just said if she doesn't call back that a lawyer would get involved and Good Luck, I told her not to call it back since its probably a scam so we are going to ignore it and hope this person stops and goes away.
