Naturals — Hair Spa price

I had gone for hair cut today. They told my hair is getting damaged so better do hair spa. So I tried that, would be given an anti hairfall spa and they washed and applied cream, kept for 15 minutes and the spa is over. I have paid the full amount ie 2950 for a 15 minutes of hair spa without a spa at all. This is not the first time i am having spa. But never had this horrible experience.
Kindly tell me why would I have charged this much price and the price is just 1100 in menu card but they charged very high amount. So please check and send my amount back.
