We are paying for an alarm that does not work

On the 27th of October I paid to change our alarm system to have pet friendly sensors installed. This was completed in the next week. After this I set the alarm and it went off several times. We just assumed that the cats are making the alarm go off by maybe jumping or something like that, but two areas went off at the same time. The technician came out to look and shouldn't have as he was very sick and simply said that he can't do anything as he needs to see a pattern to understand what is wrong. He asked me to keep on using the alarm. Every time I went out the alarm went off and drives the neighbors and my poor cats mad. I phoned again as they never followed up and asked them to fix it. The same technician came when my **** was here and nothing changed. No feedback so I phoned again and still waiting. I have to say that their service has been terrible. It can take more than 10 minutes every time just to get through to someone. We ask that they please return our money for all the months that our alarm system has been faulty and act immediately to fix our alarm.<br>
