Well, I've finally done it, my order is cancelled
This is the reply I got from Toyota when I asked what the cancellation process was:
"I'm very sorry to hear that you wish to cancel your order for the GR86. We do understand that we have not been able to uphold our usual standard of service due to the extremely high demand for the GR86 and we do apologise for the disappointing experience.
Please feel free to respond to this email to confirm you would like me to process your cancellation, once confirmation from you is received it will take 3-5 working days for your reservation fee refund to reach your account."
And here was my reply just now:
"Yes, I was surprised that the online buying process wasn't as good as expected, but it could easily have been eased by contacting the people with deposits down, as promised in the original confirmation emails.
The delays then inevitably became online rumours as nothing was coming through from Toyota to explain the issues.
I think that a statement made to those with orders pending would make a big difference as there are plenty of other people who have either cancelled already or are seriously considering their options.
So, as sad as I am to write this, please cancel my order and process my deposit refund as soon as you can."
