everything was just wrong from the beagining

I am not happy with the services I received at avis specially for a company that's deals with customers every day you expect a good customers services....my biggest concern was that the car that was sold to me I was not informed that it's does not have a spare key of which for me it's was an inconvenience for me because the key was my biggest concern or feature and the benefits there's lot of deals I declined because of the key.... when I went to fetch my spare key that was the only time I was told that the key will have to be made again and on top of that again I was not told that the key I'll get it's the one with out the mobiliser or censer, my car had a full tank when it came back it was half tank the person who fetched the car used the air con, why do that with a client assets knowing very well they won't full up the car there's a lot that am not happy about if no one get back to me or take this matter seriously I'll have no choices but to contact speck out and sort it out for me.
