No service delivery or communication!

I received a phone call to advise the matrix in our cars are discontinued and need to be replaced, not once was mentioned the contract will be extended for another 3 years, had I known this I would have never agreed due to poor service delivery from Matrix! Then I was advised that I will receive a link with passwords for the new system, 3 weeks later and nothing as yet, even after numeruous phone calls and even asking the manager to phone me! NOTHING! And this is a company that are suppose to track your car and they dont respond! And then they even debited my account with both units and again I had to phone and they advise they will fix, but with the reviews I have read this company seriously need training on customer care!
