Naturals — Charging more amount than mentioned price on menu

We are from jawahar nagar, Hyderabad. And it's a study centric area where mostly students reside in.
Got service from Gandhi nagar naturals salon beside SBI. The service was ok but they've been charging too much. The actual price for threading was 40 whereas these guys looted INR 177 for just eyebrows and upper lip threading🙏. It's not just once I suffered, everytime the same amount they are asking.Please resolve this issue as this degrades the fame of Naturals brand.
