Terrible customer care

DO NOT RENT FROM THIS COMPANY!!!!!!! They have terrible client service. I returned a car that i rented on the 25th of November. It is the 13th of December and i've not received my deposit back. You phone their customer care line they let you hold on for 45 minutes before someone answer the phone. Eventually when the phone was answered the consultant promised to send the authorisation letter that is needed to Capitec, but she never did. Clearly AVIS is in the business of making empty promises to clients. Phone again, then i was waiting for another 20 minutes for them to answer the phone untill my airtime was finally finished. This is all after spending a week phoning them and being send from one person to the next person but nobody is being able to help. They dont actually deserve the one star that i gave them. They deserve no star.
