Car Rental fees taken off, but deposit not returned

<p>I rented a car from Bidvest in Port Alfred on Saturday, 31st of December. They took a R5000 deposit for a single day rental (in itself a ridiculous fee). </p> <p> </p> <p>I returned the car in Port Elizabeth on the 1st of January. On the 2nd (also a public holiday), they took an additional R999.88 off my account, having received NO invoice. I then phoned their helpdesk and was told to phone back tomorrow (no reason was given for this). </p> <p> </p> <p>I finally received an invoice from them on the 3rd explaining the rental fees. I phoned them again regarding the deposit, which has still not been returned and was told that it will take 3 - 4 WORKING days to return my deposit. </p> <p> </p> <p>This is completely unacceptable - if money can be taken from my account on a public holiday the day after rental, why does it take 3 - 4 working days to return the money to my account?</p>
