So disappointed

I must say I am extremely disappointed with the service received from Tempest Car Hire. From the minute I walked into the offices at the airport I could see how unprofessional the company was. There was one person working behind the counter and I had to wait about 30 minutes before I was attended to. Now that I have returned the vehicle, I am still waiting for my refund for the deposit which will now be a week since I returned the vehicle. I called to find out what is happening and could not get clarity on the matter. More than that, I returned the vehicle with a full tank of petrol and was advised that they filled up another R120.00 of petrol which will be deducted from my refund. I don't even know how they could have filled up another R120.00 of petrol to a full tank, it's not possible. I must say, it has been a frustrating ride with Tempest and I will not use them in the future!
