Haha! Yes, business ownership is grand, isn't it?!

At least in 3 years doing this, this is really the first time I have had to deal with it. As for suspending service until I am paid, that shouldn't be a problem since I have not spoken to them since May 26. As I mentioned, we went 2 weeks later on our regular day and they were not there. That was 2 weeks ago and I have not heard from them at all. No email, call, nothing. I have left numerous messages. I've had people "double up" before, so I am used to that. That is what I was expecting when we got there 2 weeks ago to clean. However, they were not home and I haven't heard from them since.
I am going to send the invoice tomorrow and see what happens from there. Thanks a lot!
