Supercuts review: pricing

I have been going to Supercuts for 4 1/2 months twice a week. Today the manager tells me I have not been charged enough all of these months. She increased my visits by $9.00 for each visit. She did not apology. She was not kind about it... She acted as if it was my fault somehow! She was very rude and unprofessional. I will never go back to Supercuts nor will I recommend them...
