Car track

My contract is barely 6 months old but I am very unhappy with their service, it took them a month to repair a unit, during that time there was no contact made but yet the debit continued. I called the other day and went from one person to another never-mind the time spent holding but still no assistance. Also the customer is responsible to ensure that the unit works, they don’t monitor the unit but they debit!! What are we paying for?? Stay away from Car Track if you want to have peace. Also they don’t make contact or follow up on complaints!
