I've run across this problem several times in the past, and have never found a fool proof method.
The alarm went off this morning. The owner's cell phone was called. He is fourth of fifth on the call list, yet nobody else was called. He's only 1000 miles away.
Problem 2 (now resolved because I moved). I was on the call list, and received calls for several years after I closed sold the business. I told them I would call the police if they continued calling me at 3:00am. They never stopped, until I moved.
Problem 3. They won't change the call list. They say they will, but the next time it goes off, they call the 'old' number again.
Three different companies.
Any ideas?
