Don't change your number because of them. Make their scam be known and contact the DNC registery and the information that another has posted above. Make it hard for them to continue as they will get someone that is nieve and need others to watch out for them.
I got a message froma man named john snyder(I think that's what he said)it was very hard to understand him with his middle eastern accent. Claimed I was named in a lawsuit with the last 4 of my ssn. Said he was from the criminal investigation department, but didn't say who the siut was from. I needed to call and get it resolved or they would call the local law dept. I have never received anything by mail about a default account of any kind. I'm not sure if this is a scam or not, but it doesn't sound legit.
This is a scam..for some reasons they got people's last ssn not the whole number. Collectors in the US don't threat anyone because they are affraid of lawsuit. I got the same thing, but because his name is James something he's not from the bureau department..these people have nothing to do but calling people for money. Just ignore the phone call or hang up. They are thieves that the US are looking for. I know they have my ss#, but they can't do anything about it because they don't have all the information. Someone named James F$#% called and left me a message stated that they had a lawsuit against me, and that's all. Here's the number they left 202-239-8250 FAKE!!
I just received the same voice mail from a John Synder, very hard to understand him. Said he was with criminal investigation or something like that. Said that I needed to call him or they would contact my place of employment. This always make me worry
