Who called from 2155867517

Just got call at 9:36am, called back and message said "thank you for calling the fund raising center, unable to take call"

Asked for Greg, my father, I asked who was calling and they said they'll try back and hung up.

By now they should all know that I don't answer unrecognized numbers!

Hey guys, DON'T call back!!
You get put on the sucker list..
Even if you don't answer, it's now a working number, gets sold immediately to more spammers, you get more calls...
If you're put on sucker list then you have more problems...
And gezz don't tell them ANYTHING.
Don't say anything.
One place made a company named "I don't know", and they asked you a question that you respond that phrase to, now you have agreed to something for the "I don't know" phone company...
Just block!!!!

keeps calling my cell number. tries to ask questions so that I give the answer 'yes' on a recorded line. that is NOT going to happen. I hung up.
