Naturals — Card was charged excessively huge for hair wash

Address: Banjara hills road no 3

My card was charged excessively huge amount, i went to Naturals Salon banjara hills Road no 3, staff was firstly too unprofessional and gave a bad treatment to my hair, the lady was frustrated and blabbering about other customers and told me that my hair had lots of tangles and its literally wasting her time, she combed too roughly on my hair, I literally had to ask her to slow down for 3 - 4 times, and after that I forgot to take the bill as I was rushing for cab, bill was not provided at the Salon,
when I checked my message at home I saw I was charged 7, 080 rupees for just hair wash, I called multiple times to get the bill they denied and argued with me and was not ready to send me the bill saying they dont find me in their datatbase, (ofcourse because they were planning to manipulate the salon system and didnt record my name), I have call logs to show how many times I had to call them, and after so many calls i spoke to the manager and finally bill was provided. And when i spoke about charges they kept on disconnecting my phone call. i dont know what to do, i had attached my bill in the attachment.
