Desk assistant loaded the rental with obscure insurance charges - Personal Accident Insurance, Personal Effects Insurance and RSN (which I have never heard of) without asking us whether we wanted it and without telling us that he fad marked them as if we had accepted them. Unfortunately we were so jet lagged and my wife (who signed) was suffering extreme pain due to Lymphoedema did not realise. The desk assistant had an impenetrable accent and whispered so we had extreme difficulty understanding him. We only realised that all these extras had been added when we received the bill at the end of the rental which is 50% higher than the amount that we prepaid. My wife is registered Avis Preferred but this was ignored and we were assigned the crappiest vehicle that there ever was which had not been cleaned and the carpet on the drivers side had a hole in it through to the metal. The car had numerous dents and scratches. My recommendation would be to read the reviews for other car rental companies and take your business to a company other than Avis.
