keep getting calls from this number "call us back immediately"

Thank you everyone for the helpful information. Its great to know people are watching out for each other. Stay safe!

My mother just got ANOTHER call from these people.  I was livid and called the law firm and gave them s**t.  I have also called CRTC - DO NOT CALL LIST (her number was registered) and reported them 1-+1 866-580-3625,then called PHONEBUSTERS - THEY DEAL WITH FRAUDULENT PHONE CALLS 1-+1 888-495-8501 and will be calling THE LAW SOCIETY OF UPPER CANADA 1-+1 800-668-7380 shortly to report them. PLEASE - anyone who gets calls from these morons report them to ALL 3 instituions. Unfortunately, they have probably ripped off countless people and it needs to stop.

Got a call from this number today from an automated system that put me on hold then asked me to leave a message quoting a case number.  Have no case number or outstanding debts.

i got several calls and vaicemails from them in the past few months (all automated calls, no actual person).
today, as i was writing up a report to send in on them, i wanted to verify the number and called it again.
this time a lady answered. I asked :"who are you?" she said "Natale Law Firm".
I said, "why do you call up people and leave automated messages?"
she said: "what number is it that we called which you are asking about?"
i said: "you're funny, aren't you?"
she said: "well then we'll have to call back when we have your number."
i said: "the police might call you first".
she said: "that's ok"
i said goodbye and hung up.
this just goes to show that not only are they a fraud but that they are used to people calling back upset at them and they just calmly ignore you and will continue to call.
i was actually surprised that someone answered...
has anyone else here ever gotten an answer? maybe try calling today and see if you do too...
i sent a complaint to phonebusters but the only real place to complain is the police and i doubt that would do any good if these guys are around since 2005 and are still not shut down. too bad.

if anybody got a chance to know what it is please let me know, because i am getting these kinda massages like everyday. email me @ dude_sexy007 @ yahoo.com thanks
