AQUA HAIR - CHATSWOOD, NSW

My wife asked to have her hair permed (curls) which took the salon 6 hours to do with 'treatments' they said were necessary. After the 6 hours my wife's hair is still straight and there are no signs of any curls. He also burnt my wifes hair, giving it a very nasty burnt smell. The stylist said that it is normal and that it is my wife's hair that is badly damaged and unable to be curled, when we have done it before at a salon around the corner. He then later admitted that it was his fault, and would be happy to re-do the whole thing within a weeks time.. My wife is concerned because her hair was burnt during that session, so does not want to return and potentially have her hair damaged even further.
The stylist also cut my hair, but advertised falsely, stating it would cost $20, but charged $45 for my hair cut stating that it is because he is the senior stylist, yet he was the only one in the store.. He also did a poor job and has left my hair uneven, and even too short in some areas on my head.
I took a day off for myself and wife to pamper her for her birthday, as it isn't easy for us to travel to Chatswood from Blacktown, which isnt easy bringing a 1 year old boy to spend 6 hours for basically bad smelling hair, no change in hairstyle, and a shrewed hair cut is well below standard. They said we can come back to re-do the hair, but frankly my wife and I are utterly disgusted with the salon and do not wish to return.
I have tried to negotiate with the salon and asked for a refund, even a part refund since they did spend time to try and provide a service, and instead they refused and state that they can only re-do my wifes hair. I have to lodged a complaint with NSW fair trading.
When I told them I am not happy with the service, they said I can 'go complain to the police'
It was also very hard to communicate with the people working there as their English is very poor, and after reading the fair trading website, I feel they may have health and safety violations.
