Keeps calling, at various times of the day, then hangs up when the phone is answered. Called them back, to be told they could find me further education classes in my local area. I said no thanks Im not interested, they asked to speak to my wife and for another number they could contact her at. I told them no can do. I told them I was on the do not call registery, they said they got my number of the internet. To which I replied, yeah I know how that works, don't call here again. Filled a report with the donotcallregistery and the FCC. If they continue, Ill report them to my phone operator as abusive but silent calls that the perpetrator( Global Crossing Local Servcies, Inc ) will not cease from making.
