Its an ad firm. Just tell them to put your number on a do not call list

Someone from this number has called me 3 times today (Feb 19th).  I answer the call and no one answers me.  There is then a click.

.....caller calls and does not respond....

Male sounds like 24-30yrcouldn't hear me so asked me to call back decided to do some digging and found this website wanted personal info  which i wouldn't give  which included address, visa ,  etc

Pnoned several times and I didn't answer. When I did answer, there was no one on the other end.

Now when answered it was a fax machine. I use my home number in joint with a fax. I'm guessing they heard it before now want to send fax's
