Who called from 3212410487

Someone called me from this number today and it only rang one time.  I'm not calling it back, not sure if it's part of the "One Ring Scam".  Going to block it - number doesn't look familiar - everyone I know has a special ring and this one just rang.

I received the same call from the same number. It's to a credit reduction company. Advertising.

Just received another call from this number,but my phone never rang - maybe because I have it blocked on my phone?

this number calls frequently but never leaves a message. very annoying.
