I get two calls each and every day -- one on my cell, one on my landline.  I guess that there are people gullible enough to swallow their story, or else these scamsters wouldn't be working their phones.

Called my cellphone yesterday, left no message = blocked!

Called my cell at 1:12 pm today. All calls to my cell number, except for those in my contacts list, do not ring through but hear my voice message and are given the opportunity to leave a message. This number has called before, but no message is ever left. Wish I had this same feature on my land line.

STOP CALLING ME!

I answered with "Hello" twice, and then they hung up.
