One thing I have learned over the years is that if I called earlier in the day and haven't heard from him by about 4:00, I call back and let his secretary know so she can remind him. I call then because the phone lines shut down at 5:00. Generally that does the trick. He's been known to shuffle a message under papers, and one time it was actually his secretary who got crazy busy and forgot to give him the message. That was really unusual as she is a fantastic secretary. She actually remembered what she had done after she got home that night, called him at home, and told him to call me. Anyway, address the issue with your T so the problem can be rectified. He needs to know how you are affected by his lack of response.
