Poor service, No communication and just frustrated

I've had a terrible experience so far with Matrix Vehicle tracking.

They installed 3 units into my car as well as a panic button on the 24th of December. I've noticed on the same day that 2 of the units is not working as expected, and sent an email to their repairs email address. Two weeks later sent a follow up email and still awaiting a response.

I've also discovered that my panic button in my car does not work. After holding the line for around 20-30mins I eventually got ahold of someone to confirm the panic button is not working, and that she will escalate and book something to have this sorted this.

I have since then, not received any communication from them around when they will come and fix their units in the car, or the panic button.

You won't be able to reach their call centre at all without a 20-30 min wait time.

I am very dissatisfied and unhappy with their service thus far.
