No response from Discovery

After waiting about 2 months for an installation date to fit DQ Track, it was installed on 5 January 2015. They said it would be working within 24 hours. It's now a month later, I have called 4 times and was told they would investigate and call me back. I also emailed the branch manager at C Track (they installed it) and he told me to contact Discovery. What a joke. Still no response from Discovery. Do not fall for this as they do not know what they are doing. I am cancelling my policy.
