Some guy calls almost every day and asks for my relative. Would not tell what it is about, and just keep calling.

Caller ID came up as "Local Call" although the 205 area code is many states removed.  The Caller said my last name, I asked who was calling which he again said my last name.  I asked if he didn't want to tell me who was calling what it was about.  He asked why I didn't want to talk to him about local issues.  I again asked him to identify himself and he hung up.

 I called the number back and got a really scratchy recording saying it was the "Childrens Cancer Network".  I doubt this is a legitimate call based on the callers behavior.

this number keeps calling my business phone,  each time a different person, I am on the national do not call registry, so today I ask who is this, he said "Justin with health watch"  I told him non to polite like that I had requested they do not call me , he said he was not aware of that request. and that they would not call again.  We will just wait and see

Does anyone know who this is?

The Caller Id comes up with Birmingham, Al with the number of 1-205-332-3884 and I noticed it's the same GUY everytime and has no consideration for anything. This Same guy calls everyday around the same time of 10:30am and Around 2:05 pm and sometimes at 8:30pm. He asks for the same person and will not talk to anyone else. He claims it's a courtesy call. If that was the case them he can talk to me so I take it as a SCAM. This number is already reported and my next step is getting the number blocked.
