Shocking service

For the last two weeks now i have been dealing with a faulty unit, i am getting called every time i try log a business trip and getting told i am sending a panic signal, despite requesting at least 6 times a day that they get a technician to call me, i have spoken to the floor manager twice and no surprise i am still getting these calls daily and no one has contacted me to sort it out. The add to this in downloading my log book it is apparent that not one of my business trips in the last year have been logged, despite always logging it. Clearly Matrix has lost it grip on the market and clearly just don't care once a customer has signed up. I will be can cancelling this contract due to the useless service!
