I am writing to express my disappointment with the service I have received from Cartrack as an existing customer. Over the past three days, I have been subjected to a frustrating and unproductive experience regarding the fitment of a new device in one of my trucks. Despite spending a total of five hours on the phone with their support team, I have been passed from pillar to post with no resolution. I was informed that the system is rejecting my request for a credit device, stating I can only obtain one for cash. Unfortunately, they have not provided any reason for this decision, leaving me feeling frustrated and unsupported. As a longstanding customer, I expected better service and clarity regarding my situation. This experience has been unsatisfactory, and I am very unhappy with how my concerns have been handled. I hope that Cartrack can address these issues promptly and improve their customer service moving forward. Sincerely, [Sanele Mnguni] ***
