DUBAI RENT A CAR NO FURTHER A MYSTERY

I registered to get a Volkswagen Polo, and was offered a Nissan Sunny. This was not what I signed up for. Hence, I didn't take the motor vehicle, and was advised to anticipate a complete refund. I never ever gained this refund. Can you please update me as to when I really should acquire it? Form regardsWhen you detect your rental counter, head ther
