Dealer fitted different tyres what should I do

[paule11]

Wife had the XR6 in today to get new tyres they had Dunlop sp 3000 235/45/17 for $192 each.Made a booking Monday for 4 tyres and a 4 wheel alignment to be done today.

When she went to pick it up they only had 2 Dunlops and had put on 4 GT Champiro HPY tyres.We were not advised about this it was 4pm when she picked it up.

We have been happy with the work done previously but this time are a bit shocked different tyres and one wheel has an obvious semicircle scratched into it.

The original quoted price for the Dunlops with a 4 wheel alignment was $828 the price for the GT tyres was $795 and it was only a front wheel alignment we wanted a 4 wheel alignment as we had our diff bushes replaced last week.

Does anyone know anything about these GT champiro HPY tyres?There does not seem to be much on the web about them.

How would you approach this I have never heard of someone getting a different brand tyre without being asked first.
