Diesel Torque - No feedback or Response from owner

I have been sending Craig WhatsApps and still get no feedback. I spent a lot of money and still not getting any feedback. I changed what he suggested and still have the same issues. Sent messages with the info he required, and just no feedback. 24th of March I really would like to use the system, but getting these errors every time, I have to stop, switch off the bakkie, and carry on till it is giving problems again Will you please make suggestions on what I am standing to do about a system that is not working and a waste of a lot of money invested into this 25th March, still feedback no response Not sure if you listened to my response to you question a while ago.
