They have no idea what customer service is

The people who were meant to come and install the tracker in my car were almost 2 hours late. After 30 minutes with no sign of them, I had to call Car Track to find out what was happening. The installers eventually made contact with me, saying they are late because they had went to go get food. Unbelievable , I know!!! As they were installing, they were playing music loudly in my car. I was inconvenienced and they didn't even show any remorse for being that late. They basically didn't care.
