Called and left a hangup on my voicemail, third one in two days. One of these days I will answer and mess with them because it actually is satisfying to punk them into thinking they have called a completely wrong number.
I get calls from these pieces of s___ at least twice a day. I have fun with them by speaking Chinese to them or asking them for their name, social security number and DOB. I always ask for their credit card number because I charge $50/hr for my time. They usually hang up.
