Good car, booking, drop off. Poor pickup. No email confirming car accepted with no issues on return

A map showing where the car is located would really help we spent ages lookING for the car. Although my fault I was so busy looking up at numbers that I missed a step by the lifts and pushed my father in the wheelchair over the step (although it has a tape it is faded and if looking up is very easy to miss) and he fell out and banged his head. Why does the alamo sector have a reverse numbering scheme to the rest of the whole parking lot.
