Studio 20 Changed credit card amount Franklin, Tennessee

My husband got a $15 haircut and left a $5 tip so the total was $20.  They charged us $65.  When I called the lady she immedietely said oh I did it I added to many zero's?? How does that make sense.  She actually changed the 2 to a six and added a 5 to the end hmmm.  She said I refunded the difference so I checked she did refund $35 so there was still a $10 difference.  She said oh well tell him to just come pick it up or get a free haircut.  Not likely lady.

The whole thing sounds very fishy to me.  I'm sure most people wouldn't even notice and an extra $10 from every customer everyday really adds up.
