Who called from 9712201239

Called today, I didn't answer, caller didn't leave message
Caller: john dester

I received a call to my cell phone and answered and said hello and no one was there.  I dialed back and it just rang and then an option to continue the call or to let them know if you do not wish to receive further calls. Some type of tele-marketing--sounded like for awards or rewards--hard to understand

I have received calls from this number the past four days and I can not clear them from my new phone, plus I don't want whatever they have to offer.
