ZERO CUSTOMER SERVICE

My remotes stopped working in October. A call out was scheduled and the problem was supposedly fixed. A few weeks later the problem started again. Call out scheduled and they came out. The technician did not give me any feedback and when I went home the alarm was not working. I had to call them to find out what was wrong and they said they did not know and would have to come back. When I asked why they did not give me any feedback, they said sorry they should have. Technician said he would have to bring the Technical Manager - I had to phone to find out when this was going to happen and only after throwing my toys has an appointment been scheduled for Monday. I have asked twice for someone senior to call me but to date no one has. Typical response of a big corporate - ZERO CUSTOMER SERVICE!!
