Awesome Unisex Salon - Noida — Hair coloring

I did hair coloring from Awesome Unisex parlour - Noida 15 days back and paid 1500 bucks for that .Hair coloring was not at all prominent .My total money gets wasted.I again re-visit to parlour and now they are demanding 800 bucks more for hair coloring. They are cheating their coustmers and their behaviour towards me was also very bad.
I don't want to do hair coloring again just want to raise a vioce against these parlours.
Hopefully , I get some justice and they'll admit their mistake.

Thanks
