The wimps laugh at you cause you get frustrated. The best way to frustrate them is to ignore them and block their numbers. Everyone should do the same, and then they'll end up getting frustrated. Who cares if they laugh or not, just ignore them. Giving them attention will waste your time. But if you have time, curse them out, play around with their heads, and waste their time.
Since this was the 8th call in three business days, I kept playing along until I got a live person on the phone. I had tried to press #2 to be removed but that was a joke. The person answered "Security Technologies". She asked if I was interested in speaking about their systems and I told her " no I just wanted the company name so I could tell the local District Attorney who was calling me so often". I guess they must be having phone issues because the line went dead. I have ekpt the calls noted on our caller id if needed.
