I Took my car in for a service at Big Rock Toyota. 

I confirmed before the service that it was a capped service price of $426. 

Big Rock Toyota called me during the service and said it should have a brake fluid flush and a windscreen blade replacement and the injectors should be cleaned and that this would increase the service price - however I advised that I had all of that done last service in Adelaide, and I didn't want any of these things done again. The fact that the service team wanted this done even though it wasn't required rang alarm bells. 

I was then called back shortly after and advised in order to do the wheel balance (included in the service price) they would need to do half an hours work to wash the mud off the wheels (not included) this was going to cost $80. I approved it because I was going around Australia and needed the wheel balance done and didn't have time to mess around. 

However I thought about it afterwards and it was obviously another attempt at upping the capped price servicing. 

As I have always owned 4wds and never recieved this 'Mud cleaning' charge, I called my local Toyota (Launceston Toyota) for advice and they said they would never charge for that and it shouldnt have been charged. 

So Its obvious that the couple of times they called they were just trying to get extra money out of us any way they could. They eventually succeeded.

When i spoke to the service manager of Big rock, and advised I was unhappy with the 'mud cleaning' charge, and that I sought advice from my local Toyota dealership, he advised well if Launceston Toyota doest charge for that then they don't have good business practices. He also kept repeating 'you approved it.'

Worst Car service experience in 20 years.
