PATHETHIC SERVICE, DEPOSIT REFUND DELAY!!!!

First time using Thrifty Car Rental & most definitely the last. Been waiting for 6 days for deposit refund with no communication. Called the Durban Branch and they advised I need to contact their Head Office. Called twice , 2 hour waiting in a queue , spoke to a Naomi who keep on transfering me to the holding deposit dept and after very long holding time then im right back at her answering again. This is extremely frustrating and worst services ever to say the least!!!!
