Refund of deposit

<p>I hired a car from the 15-19 of December 2016. During the sign on and hand over of the car i was made to sign a declaration wich included the costs and insurance for tyres, windscreen etc.</p> <p>It so happened that the tyre got damaged. After a month i contacted Hertz Rent a Car regarding my refund as they had said ill receive it back within seven to twenty one working days. They told me they're still claiming the tyre damage which I had insured and they're charging me an admin fee of approximately R800 of which I was not told about.</p> <p> </p>
