Poor counter services!

Poor counter staffs. The car we booked was not available and they tried to downgrade us to another car that can never put all our luggages inside. We booked a bigger car foreseeing we needed to put in quite a number of luggages. In similar cases in the past, we would be upgraded to another bigger car only instead of being pushed into a smaller car. 1, pirce is not the same. 2, it simply didn’t work! It took us 30 mins. We insisted and then was asked to wait for another 30 mins because they needed to wash the car! I think all these should have been managed better given they are clear what kind of cars customers have booked! I will go with another car rental company next time!
