Good Luck with getting your deposit returned

Wrote a previous review but after they rep**** that they would sort it, still waiting for my deposit for a car that was returned more than a month ago. Quick to take your money but getting a refund of deposit? Good luck. All they state is: Your complaint has been escalated to the relevant department for urgent investigation and resolution. I don't understand as I gave them all the reference numbers for payments. What is there to investigate? Poor service!
