Received a call from this number stating they were from the IRS & that I was going to be sued if I did not contact them back.

Said this was a final message to notify me the IRS is filing a suit against me and to call this number back. Number on caller id was 323-455-7154

Same number called several times but do not ever answer as I do not know this numb, but they keep trying, and yes, the are filing a suit against me as well and told me to call back..I just feel bad for our seniors who get scared and do call them back. Sick people...Yep. 323-455-7154

I just called the number back and guy answered the phone saying he was from the IRS and that i was being sued and its attempt to collect a debt. He told me i was notified by mail which i never was and also all my takes are paid so i know im not getting sued. If i was there would be a letter by mail that i would have to sign for if i dont answer that letter then they will put a levy on your account but at no time does that IRS call people to collect taxes. He asked for my address but i said if you know where i live then you tell me what my address is. He proceeded to tell me one of my old addresses which i said your incorrect becasue the IRS knows where i live and he said this is the correct address then asked for my correct address i said your the IRS you should know it if you dont i dont believe you. Then he got mad and wanted more info from me i said to him im sorry but i will not give you my information unit you tell me why it is your calling. He could explain that to me. It surely a scam and they will steal your identity if you give them your correct address. I hung up on the guy like it was dropped call and have to get a phone call back. If that happened in the middle of a real IRS call they would call you back immediately. Believe me its not the IRS and this is a scam

You're absolutely right...it is NOT the IRS.  Here is the IRS site with information to help people avoid these scams:
