Bad service

Booked an automatic vehicle online on15 April 2015. On 22 April, I called the call centre and told them that I'm wheelchair bound and requested hand controls on the vehicle and indicated that I will collect the vehicle at the Centurion branch on 27 April. The agent promised to call back with further details but never called back. I've called Avis call centre back on 24 April to find out why nobody is getting back to me and see if I will be able to fetch the vehicle on 27 April. The call centre agent then told me that they don't have a vehicle with hand controls available and told me that she doesn't know when one will be available either. The agent should have just told me on 22 April that you won't be able to help me and then I could have contacted another supplier. Really terrible disappointed in Avis as well as the way your call centre agents handled the situation. If people with disabilities are treated this way by Avis, I will rather use another rental company who wants to help and assist people with disabilities.
