Dummy (false) Button on 2018 Toyota Hilux Steering Wheel

I purchased a demo Toyota Hilux Extended Cab 2.8GD6 A/T 4x4 on Friday the 19th of October in exchange for a Ford Ranger 3.2XLT. On Saturday the 20th I needed to make an urgent phone call and pressed the SPEECH button on the steering wheel to ask the vehicle to contact someone only to see that the multimedia panel displayed a message - "Voice Recognition Not Available". After contacting both the dealer and Toyota SA, I've been told that this is just a dummy button and does not work. It worked perfectly fine in my Ford and I feel I have been ******* into believing the button was operational. What serious automobile company inserts a dummy (not operational) button on the steering in any vehicle! I believe that Toyota should upgrade the software or install compatible systems in order to continue inserting this button in vehicles. Very disappointed!
