CHARGES TO CREDIT CARD

I hired a car for the weekend 3rd April. We were given keys for car and no-one checked car with us. We checked for damage to car (dents, tyres, windows etc).<br> <br> We were about 10km's away from the airport when my wife pulled down the passenger sun visor and noticed that the vanity mirror was broken... Who checks for damaged vanity mirrors? On returning the car a few days later we advised the return clerk, but we were STILL charged R1244.68 for the damage. I have advised Avis that this is unacceptable as their staff have not done their jobs correctly and now I am being penalised... I Have advised Avis that I expect a refund for the charge on 3rd April.<br> <br> 3 days later & I still have no answer even though they have had the funds for nearly a month and it is 25th tomorrow, so I will be charged interest on my credit card for this charge.<br> <br> Avis are quick to debit but VERY slow to respond and credit
