Who called from 5085417892

Received call from this number about 30 min ago on my cell. Who/what ever this is hung up and did not leave a voice mail message.

They said they were calling from Chevy Chase bank to reduce your credit card rate as low as 6.9% - unsolicited calling - I hung up

I don't know who this person/company is, but they need to stop calling me!!

Received a call from 508 541 7892 on cell.  I don't answer calls if I don't recognize the number. They left no message.  Is there a do not call registry for cell phones?
