The caller, an Indian woman said she was the from the Internal Revenue Services and did I know that there was a warrant out for my arrest.
Immediately I knew it was BS.
Then she said I was being recorded and do I agree to not say a word or interrupt until she was finished.  I said Maybe.  She said what do you mean??  With a serious tone I didn't appreciate.  I said I will dispute anu falsehoods immediately.  Then she really became combative and said, now yelling at me, do you realize that you will be arrested???
I hung up, blocked her.  Although blocked, the calls still show up on my phone log.
She called a total of 11 times.
Good thing I have a few cop friends to look into it.
I called the number, blocking mine and there was a recording of a British woman, saying no one is available to take the call, leave a message.

Do consider getting a call blocking device or phone.. You can google them and many are around $40.00 or so.If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.

Just recieved a call fron this number. Indian/Pakistani acsent. Asked if I recieved mail for a warrant for my arrest from the FBI. After a few seconds, I asked him if he knew the last four of my social and he could not since it was being recorded and would be used in court. They I asked what juristriction was the case be handled by? That stumped him. It was obvious he didnt know the what JURISTRICTION meant. He finally gave my my home address for it and I laughed and he hung up.

This was happen to me a hour ago.. the woman leave her messages on my phone and said I have IRS owe...

I received a call from 904-638-380 number today. From IRS they said. They scared me tell you the truth. But when it began to talk about the cash money, I understood that it was a scam. I called back. The guy answered the phone. I talked with him a while. Hi is not scared of anything!!! He just don't care!!! Can authorities do something about it??? You can find the person in Florida. As I saw in white pages this number I came up with Stacey F Thinn. So what to do?
For some people it will be devastating to receive this kind of call.
