Cartrack

I am sharing a review on behalf of the company I work for, who uses car track. We had 2 units in 2 vehicles that were sold. We asked to hardlock and reinstall units into 2 new trucks. We have paid, completed forms in February. No one up until today, we now in June has been to reinstall units. They don't answer emails, they don't allow me to speak to a manager. It is a true nightmare. But monthly they debit orders are being taken. I would like to know why it has taken 4 months? Is this how car track does business?
