Shocking installation and sub standard units

<p>I had my unit de-installed and reinstalled on Saturday, 5 th Aug 2017. Firstly, the installation technician forgot to replace spares and bolts from both vehicles. Then to TOP all that the reinstalled unit stopped working today!!, 7th Aug 2017. May the record show that my car is classified as High risk.</p> <p> Now my new car will have to be pulled a part a second time, again risking damage to components and technicians that forget to fasten bolts. I demand an answer from a manager or a senior person because this is absolute shocking. As a consumer, we pay Top dollar for a substandard service.</p>
