Enterprise Rent-A-Car

I am a regular customer of Enterprise for years. When I picked up the car at Stansted Airport on April 18, 2015, the clerk told to examine each tire very carefully. Which was odd since they never told me to do this before. With little spaces between parked cars, I could only glance standing up that there is no visible damage to the rubber. When I returned the car the next day, a clerk brought out a lamp to specifically examine each tire and stated that there is a hairline cut in one tire that I could hardly see it with the lamp. This is a 1.5 day rental and I never parked by the curb and there is no way it had a chance to scratch against anything. Now that costed me 127.99 pounds for the alleged damage which I have yet to see the report or a picture.
We believe that it is a set up, since the clerk never lent me a lamp to examine the tire with me in the first place. So if you must rent from Enterprise, please, please be very careful not to get ripped off by the tire scam, particularly at Stansted Airport.
