Keeps calling my number does not leave a message and when i call back i only get a busy tone.

I received a call from this number.  When I answered, there was a recorded message regarding a lawsuit against credit card companies.  An offer was made to potentially forgive my credit card debt, depending on what credit cards I hold (which are none).  Press 1 to see if you are eligible, press 2 to be removed from the call list.

Robo call trying to giveaway/sell medical devices. Got through my "nomorobo" on my phone. Was very disappointed. You can press 2 to be removed from call list, but I am sure this verifies there is a live person attached to this number. Tried calling back and all you get is a busy signal.
