Bill and his wife are both up in age and moving a lot slower these days. SO my suggestion, be patient and yes sometimes you will get the voice mail box no setup, but other times you can also leave a message so you just have to keep trying. You also have to realize a bunch of people try and make contact with them and order calls. I was fortunate after trying several times to make contact with them and order some calls and they shipped them within a few days.
So my suggestion is keep trying and understand the situation. They are awesome people Bill and his wife.
