Our 3 week trip to France turned into 24hours as my mother and father had a serious accident,my father lost control of his automatic car and hit 8 cars.Result my mother has 2 breaks in her leg and lacerations to her face etc.Going to be in hospital for a long time,anyway we rushed home via the Dartford crossing and in all the turmoil I forgot to pay the Dart charge.Got a penalty notice today,went online and paid what it asked me for £2.50 !!Summary.You have paid £2.50 FOR THE PENALTY CHARGE AND CROSSING FEE.YOUR PAYMENT CONFIRMATION NUMBER IS;XXXXXXXXXX.Is this correct.I thought and expected to pay a penalty charge.What shall I do?
