Fraudulent activities by Autovest Pretoria East

I made an appointment to install smash and grab. 1 week later tint comes out. Contacted Head Office and apprently Autovest Pretoria East is committing frudulent actities and installing foreign flim not Auto Armour flim. Autovest head office does not want to assist me and asked me to get resolution with Autoboss Pretotia East who was trading as Autovest. I was given an Auto Armour warranty booklet and now cannot claim as it is now deemed fraudulent. Just dont deal with these companies as you are wasting your time. Absolutely pathetic service from both "Auto" companies
