One of the worst experiences I have ever had with a company. We arrived at the agency at the Venetian in Las Vegas. Our first complaint was that there was absolutely no one at the counter along with no sign posted when they would be back. So after 30 aggravating minutes, the representative decided to do her job and return to work. She was not very friendly and was very short with us. She did not explain many options that we could add on for the car. After all this, she informed us "we were receiving a free upgrade". When we walked to our car, we walked to a Nissan Versa. This was no upgrade. On top of the lies we were told, the car was not filled with gas. We took the car anyway and headed to San Diego. We woke up the next morning (New Years Day) and had planned to see a few sights before the car needed to be returned at our hotel in La Jolla. We went to the counter to confirm our time of return (which is suppose to be 30 minutes after the rental began in the first place). Well, the rep here tells us she is only open until noon and the car must be back by this time. There was absolutely NO notice of this at all and we were NEVER informed that Avis would be closing early. The rep was pretty rude and definitely showed she did not care much about our situation. After this, she went out to check the car. When she came back, she tried to charge our rental with gas money because the tank was 3/4 full (which was more full than the 1/2 tank we got when we picked up the car). She argued with me for about five minutes and I refused to pay any extra money, especially because we were returning at 9 am instead of the 4 pm we were expecting. Any way, we ended up taking a cab to what we had planned which was $100 total. I called Avis' costumer service number and they showed absolutely no interest in my complaint. I have rented from Hertz before and I know this would NEVER happen. Avoid Avis at all costs. They don't try harder.
