Lakme — Salon guy charged high prices

I am sahithi divya, yesterday on august 14th, i went for qod hair treatment to lakme saloon, vijayawada. My hair length is mid back which costs 8500/- according to lakme prices, but in the bill the guy charged for waist and below which costs 11864/- and extra cream charges for 3 times (1016*3). He said mid back length treatment cost is 13000/- and he charged extra 1 time for cream cost, but later when i saw the bill which was sent to the phone, i realised that how he lied to me. Please give me refund on hair length and extra cream charges. Waiting for the positive response.
