Called and asked for another person in the household and I said they weren't there and they started making fun of their name and being very rude I called the number back and all I get was a busy signal. I tried asking who was calling and they would not tell me.

called claiming to be a law office and that it was in my best interest to call them... No identification of what law firm, sounds like normal collection tactics.. and not a great collector at that. Message was curt, rude, and attempt to push for call back... but offered nothing and the tactic invites more ignore than anything. Kicker to this was they called the wrong person... they started of with a name, it was not me.

harrassing calls

let it ring out

they keep calling every 5 minutes...

According to NANP this is clearly a spoofed CID. There is no such rate center starting with 200. CID is easily spoofed and it is best to either blacklist the CID (once again CID can be spoofed easily) or just do not answer calls in the 200 "rate center" range - 201 is however legit.

Calls all hours, no one there, doesn't leave message, can't return call...who is this?

Received a call on my cell phone and the woman said she was returning my call from the Family Planning Unit. I didn't call anyone so I told her wrong number.

4 calls today..

Same thing here. Calls 4-5 times daily. No ones there when i answer. Static on the voice mail. It's creepy. I've noticed this started after speaking with collage recruiters. I think this might have something to do with it.
