Zerto telemarketer hung up when he was asked to identify himself. I called back and when he answered the phone, he said his name is Matt. Matt has called 3 times in a one-week period. The first time he called, I took a detailed message and gave it to the information technology department. The 2nd time he called, he declined to leave a message stating he would email the IT guy. And now he hangs-up - not something I take personally, but I do notate it in bold letters.
