Worst service ever

I had Cartrack installed in three of my vehicles on 2020-06-16 and since day one I have had problems where I CAN NOT pin point my vehicles as there is a permanent delay. The more you explain to these people that you need to know where your vehicles are the more they tell you they understand. When bringing it to their attention that a 45 minute delay is reason to cancel and for them to remove their equipment, you get and sms while talking about the terms and conditions. You send emails to the CEO complaints and no answer. So what is the solution to this if they can't give me results. I have spoken to Browyn, the fleet manager and so many others. You have the recordings listen to them. I spoke to the technical people Juante and he send someone to check system, when reporting to him that I still have the same problem, he would have come back to me, to date nothing. Please if you can't offer a service them remove equipment and cancel contract. I have two other methods of tracking the same vehicles and they are accurate.
