I have a special place of hatred for robo calls. Not only do they annoy me on my personal phone, they plague my work phone as well. AND, I use a company calling system to call my customers (this way they don't get my work cell number and call me day and night) that is based out of OKC. So Tulsa area people see the 405 area code and ignore it. Then I get customers who get angry because I didn't call before I came out.
