Great Clips complaint: Over charged senior citizen!

I have long very thin hair. All I ever get is the bottom snipped off. The hairdressers have all called my cut a bang cut because it usually takes five minutes to cut it at most. Today someone named Sandra called me back. I had not seen her before. I told her what an easy cut I wanted. The other lady had already asked if I wanted another bang cut and put me in the computer as such. This Sandra exclaimed that that was not a bang cut and that she was changing it. When she came back I explained that it was because it was such a simple quick cut. She proceeded to say she sectioned off the cut and it was a haircut and got started. She made a big production of sectioning off tiny sections and cut my hair her way. It took approximately 7 minutes. She then charged me full price and seemed to feel real good about it!!! I’m not happy with her and will not let her cut my hair ever again.
