Bad customer service and mistrusting

After hiring a car for a duration and returning it filled and having it checked and been given the clear. No holding deposit has been refunded. After a laps of 17 days. I then called the customer line to query what is a happening. To be told I had to request a refunded for it to be processed. As well as to be told there is a backlog without any indication or email regarding this. That was never mentioned. I was told it would be up to 10 working days. So now it’s the customer responsibility after they received the car back and all is well to call after my own money. They then told me they now have a back log and it will take another 7 - 10 days. Wow. What a jokes this is. So basically if I didn’t call they wouldn’t have retuned the deposit. Not even a email to inform me of a delay or issue. I don’t recommend them. Withholding money that is meant to be returned. Not a trustworthy company.
