Bad service and total stuff up with account

<br> I stay SA. On the Monday previous to the flight I phoned Windhoek airport branch and confirmed the booking. When we arrived nothing was ready. It took them 40 min to do the paperwork and sort things out. I booked a child booster seat, and that was also not ready. They then organised something, just to get to the car and it had a baby seat for infant in. I was not happy at this stage, the guy there told me to just drive like that without seat. I almost lost it. I pay more for the safety of my child. Just more waiting...<br> <br> When I signed the last papers I told them that we were being charged double for additional driver. Which they said they will sort out. Did not happen. R5137.50 deposit was taken from my credit card. On enquiry back in South Africa the next week - I phone WHK. The R5000 was not back in my credit card. Just to get a sms from FNB on Saturday 2 May, that they took off the R5000 again. <br> <br> Wait it gets better. I filled the car when we left WHK. Drove 46km to the airport. Then they took off another R248.55 for petrol. How can a 1400 Polo use that amount of money for 46km. I complained with email to HQ, I phoned a couple of times to Windhoek. Nothing. No reply.
