I won't be using Avis again!

No convertible available on pick-up so had to stay an extra night in San Francisco and use a temp rental car with additional bridge tolls. Had to return next day where "Prestige" staff were diabolical, at one point asking me how I thought I could get a refund for the 1 day lost using the Avis system. First Mustang had a rip through the side wall of one tyre which wasn't dealy with until I checked out of the parking lot - they advised me to change the vehicle, which we had to do for safety. Therefore, I actually hired 3 vehicles! At drop-off it was discovered that the pick-up location staff had not correctly applied the exchange rate of my stirling payment and had thought that I owed a one-way fee. Initial accusations from junior staff were then corrected by the Manager with no more to pay. Both pick-up (2 days) and drop-off caused much anxiety. However, thank you to Shy at Oakland and the Manager at Harry Reid.
