Scam trying to solicit money for "charities"

Did not answer the call and they left no message. I called back, the recording said that they collect for charities but did not identify the company name.

I asked them to take me off of the calling list.

They were calling to Mr/Ms "Node", then I told the this lady claim to be from some Women ????Charity that I not Mr. Node. She said it fine, they  didn't update the phone list. I said ok. Then she said mailed a package of something, and wanted me to mail them back with a check to support them, etc...I stopped her, and asked how can I get their email if I am not Mr. Node...she firstly didn't understand what's the problem. after I repeated, she said "it's okay, someone may be confirmable, someone may be not" and hang up the phone.
WTF??
