Poor Quality Feedback

<p>To get straight to the point, my vehicle tracking device went faulty and needed to be repaired. Matrix suggested that i upgrade the unit and start a new 36 month contract as my current faulty unit was old and outdated. I agreed and the unit was replaced after quite a delay where I had to beg them to install the unit. Once the unit was installed (Free of charge as per agreement)i received an invoice for 2 months subscription, clearly a month for my old unit and one month for the new unit. I contacted Matrix a week before payment was due and requested them to investigate and provide me with feedback. Up to now i haven't received any relevant feedback and at the end of last month they procedded to deduct the 2 months subs from my account. I have emailed the accounts department with no joy and yesterday proceeded to call Matrix. No answer and the call terminates almost straight away. This is very concerning because if i am in a high jack situation, there is no means for me to contact Matrix as their contact number has issues with it.</p>
