Car not there when ordered. Months taken to refund

I ordered a 14-seater van for a video shoot I was working on with an important client for the 7th of December. I booked the car the night before & in the morning I tried to call the Green Point branch to check if the car was there at least 5 times but no answer. I even called the other branches in CPT to see if there was an issue with the phone & asked 2 separate branches to ask the Green Point branch to call me.<br> <br> I arrived at Thrifty & they informed me that they had failed to retrieve the van from the depot and it would take 2 hours to drive to the airport and back to collect it. I didn't have the time to wait for that and so I cancelled & my client was forced to hire their own van - which was bad for my business reputation. <br> <br> The manager assured me that he would process the refund immediately but I still haven't received the refund even 3 months later. I have called him on two more occasions to follow up and still nothing has happened. I have followed that up by calling customer care and they promised to call me back with a response and still nothing.<br> <br> I like Thrifty but I am deeply disappointed and would like more than just a refund if I'm ever going to use Thrifty again.
