Secure?

We have been with blue security and have dutifully paid our accounts for 2 years. Recently we realized that the control room wasn't receiving our alarm signal. After 2 weeks a technical guy came to assist. We were charged r350 for a call out that took a minute to repair a loose wire. I would like to know why there had been no testing of our line. If something had happened because of this fault they would no doubt abdicate all responsibility. Yet we are charged for everything.<br> Very disgruntled
