If you have issues with them, call them back and while the system is talking press and hold down 9 until it disconnects. This might help but i just tried it so I hope it does.
I've had 6 calls from this number today but since I don't answer calls from numbers I don't know, I have not answered. Another site says this is a spam number.
Same here! It's harrassment ! It's an automated message about student loan forgiveness. I am not only getting calls but texts as well. When you call back, it gives you an option to be removed from their list. But guess what ? You will STILL gets their calls !!! I can't get them to stop.
To stop them use a call blocking device/phone (or call blocking app for your smart phone). It will also stop those groups that are exempt from the DNC List. They're available online and start around $50 or so. http://800notes.com/nb/search?q=call+blockers

Do not answer unknown calls and do not call them back.
