Do not leave a message when they call. It's always to update some information. If they already have it why do they keep calling.
It's a Telemarketing scam out of Nevada. They call hundreds of times and always hang up in your face if you answer the phone. If you don't answer, they don't leave a message. I think they want you to call them back to see who they are and once you do that, then they start harassing you forever, because they say you made incoming contact to their number, and then they start trying to steal your credit and personal identity, or try to sell you on whatever the going telemarketing scam is, Solar Power, or Payday Loans, or whatever they think they can cheat you on.

Whoever it is they call every day for a week now. Sometimes multiple times a day. They never leave a message but when I called back from another number a lady named Jessica answered the phone but did not address it as any business. I'm sure she's a scammer.
