Avis Service Call Centre

My sons arrival by ship to CapeTown was delayed and I called Avis to advise them of the delay. Called the number on their web page for customer service CapeTown Airport gave them the reservation number and they were absolutely USELESS. Couldn't find the booking number and couldn't help me dispite the fact that I had the confirmation in writing. ! Then discovered that it was a call Centre and not the airport branch when they gave me the Airport office direct line. If I hadn't persisted and called back several times my son would have been stuck without a vehicle in CapeTown. I managed, yesterday, to get through to Avis in Durban and a Natalie Varley was extremely helpful and sorted the issue out even arranging for the vehicle to be delivered. <br> So Avis if you want to have a SERVICE call Centre ??Please train your staff ??
