I recently hired a car from a well-known national hire company. I booked and paid for five days hire. I returned the car full of fuel with no further damage. I received a claim from the hire company with pictures showing the window screen cracked from top to bottom (easily seen from distance).

I returned the car when the agent inspected and confirmed on the returns statement "No Damage" of which I have a copy. The hire company have notified me they will take full repair costs from my credit card account for additional damage shown on their photographs. What should I do?
