Complaint Review: RENTALCARS.COM

I booked a small pickup car with RENTALCARS.COM for the Carnival period, in Brazil. I did it 3 weeks before the desired dates and soon I received an email confirming the pickup, and the total rental amount was charged on my credit card. Just 3 days before the beginning of the rental I tried to print the booking voucher in the website but, surprisingly, the booking was turned into "awaiting confirmation" status! They deceived me! I paid for a pickup car which they had confirmed but the car was not available, they just gave me another car. This is a huge mistake in the reservations administration process and a radical violation of the consumer rights as the service was already paid and was not avaiable! To cancel the rental would be a disaster for me as there was no more pickup cars avaiable at the time I found out the pothole. Although they gave me another car (not a pickup one), it does not eliminate the severity of the situation, and did not satisfied me indeed. Therefore, I DO NOT RECOMMEND RENTALCARS.COM UNDER NO CONDITION, they do not know how to work, they do not honor the rental commitments and do not provide a standard of quality as it should be offered due to the prepayment they impose on their customers.
