Hidden costs

I had a bad experience recently. The sales person made a booking for me while I sit next to her desk and the amount I saw on the screen was different from the money reflected on the invoice.i tried to question it but I could not succeed. The sales people do not have name tags which makes it difficult to identify them when making an inquiry. I didn't receive the invoice, I had to return to the office. The amount of money I had to pay due to hidden costs was too much for a small car like Toyota Vitz. In addition to that I had to pay extra R100 per day because I had a code 10 drivers license irrespective of the 16 yrs I have had the license. I am disappointed since I didn't get value for money.
