Cost Cutters review: Got overcharged for child haircut and wash

Booked online for appointment at Atascacita Commons location for 6 15 Saturday October 8th. Got to location and told Josefina I wanted to get straight across haircut for granddaughter.. I explained she wanted to be snow white for Halloween. She asked if we wanted I asked if it was extra because we had just washed it that morning she said its up to you.. so she washed my 8 year old hair and gave her cut after 20 min I saw she was done I walked back to her station and asked Brielle if she liked it Josefina was taking out her dryer and I told her we dont blow dry Brees hair because it is so thick.. We were running later for B Day party so I took out 30.00 cash and asked her how much. She said 29.90.. I was in shock.. last time I took her to cost cutter in Kingwood al little over a year ago it was less than 15.00.. I paid her $33.00 (added tip) when she saw I had cash she reached across to credit card machine and pushed a button.. She offered me no receipt I would have normally asked but we were in a hurry.. After talking to friends at party they agreed I was overcharged.. I am very disappointed with this establishment
