Dissapointed Customer!!!

We rented a car with Thrifty on the 27th of April, a deposit was taken of R1,000 and we were informed that it will be returned upon the return of the car. We then returned the car on Sunday the 12th of April we were then informed that the deposit would take 3-4 working days after we returned it for the funds to reflect back into our account. It is now almost THREE WEEKS LATER AND NOTHING!!! We have contacted the branch and spoke to various consultants and the manager but no one has managed to assist us. I'm in utter dismay and disgusted with the service I have received from Thrifty, this is the worst place to rent a car from, I certainly will never use your services again and will inform everyone I know never to do so either. For a company that prides itself in giving great customer service you have failed in more ways than one, no one has even contacted me to follow up if my query has been resolved as yet or even a courtesy call to show concern for a client of yours! Can I please have the Regional Manager contact me to apologize, ensure my money is back into my account TODAY and also find some sort of compensation for all the inconvenience you have caused me and my family!!!
