Frequent hangups all hours.  Fake caller id

I have been receiving calls from this number.  They claim to be the diabetic health network.  When I told them never to call again, they slammed the phone in my ear.  According to a Web site, they are not affiliated with the Diabetes Health Network.

In a 2 day period I recieved 19 calls from 240 507 1191 Went I got so pissed off I finially picked up the phone some guy that could not speak english would not tell my who he was calling from. I'm on a do not call list but I guess thats about as good as our Healt care plan. Somebody do something about these people

Remember that when you give your credit card number to someone over the phone, if the call is to India or other offshore services, it is not illegal there for the number to be taken (no laws exist or enforced).
Operators can sell collected numbers to criminals with no liability of the original theives that started the identity theft using your information.  Every ad you reply to seen on TV services their billing from countries that do not have laws to protect you from identity theft.  Giving them any information almost guarantees problems for you.

this number called me out of the blue today.  I never answer any unwanted calls or calls I do not know.  So if the person who is calling is reading this: STOP! Thank you.
