I've been getting these calls for 3 years now. Just got one from this number today, but they've used dozens of different numbers to call me. They seem to come in waves. I'll go without hearing from them for a few weeks, then get multiple calls a day for a week or so. If you say anything besides what they want to hear, they hang up on you and you go back into the dialing rotation. These people are scumbags and I hope they all die in a fire. :-)
I have the same story. Tried a whistle, yelling, being nice etc. Now I don't answer any unknown long distance number and save it to my contacts with no ringtone after I google it. I assign these numbers a bad name starting with Z so they dont get in the middle of my real contacts. They still call but at least I don't hear it when they repeat a # and get as angry. Hate them too!
Yes, yet another chance to get scammed. I've been getting these calls on my cell phone for over two years now. Always says that this is my last chance blah blah blah.The number displayed is never a working number.
