Had a filing repaired today at Dentist and when I paid they only charged me £20.60 I thought it was cheaper than normal but thought maybe as it was just a repair and only took 15 mins it was charged at check up rate.
Anyway they have just called and said I was charged the wrong rate and it should have been £56. I paid by card over the phon (after giving the women my card number 5 times FFS!) but could I have refused to pay?
