If you ever book an Avis reservation online or over the phone, make sure you contact the office of…read moreyour reservation afterwards! It does NOT matter what you reserved online or reserved with an Avis agent over the phone because they do not communicate with the location of your reservation and will give you a false confirmation! We booked our Avis reservation online months in advance for a trip to Germany. We were to pick up our car on Thursday May 26, 2016 by 5:00 PM at the Frankfurt Hauptbahnhof. We arrived May 26th shortly before 5:00 PM and found an empty Avis booth. Turns out that Avis closed early at 2:00 PM because of a public holiday, Corpus Christi! Not once online and in our email confirmation did it mention holiday hours for Thursday May 26, 2016! Our hotel in Mainz was a 30 minute car drive away that we would have taken in our rental car, so instead we had to take a train and cab all the way to our hotel. We decided to sleep on it and clear up the mess the next morning. We called the Avis hotline the next morning to discuss our problem with the reservation. We complained about how we weren't informed of the holiday hours for the Avis Frankfurt Hauptbahnhof and had to take a train to our hotel 30 minutes away. An insincere apology was given and they said there was a local Avis in Mainz that we can make a new reservation with. Everything was kept the same as the current online reservation that we booked for the Frankfurt Hauptbahnhof to include a car with a baby seat. The reservation was confirmed, email was sent to us, and we could pick up our car from the Mainz Avis within the next two hours. When we arrived at the Mainz Avis we were tended to by a very rude female customer service rep with glasses and curly blond hair (she was working at 10:45 AM, Friday May 27, 2016). She gave us great responses like "I don't care about your driver's license, I want to see your passport" and "Who told you we have baby seats?! We don't have them" and "There are no baby seats at any other office, we are alone." What was confirmed by our new reservation that we made over the phone with Avis, a car with a baby seat, did NOT exist at the Mainz Avis because they had no baby seats. And they made no attempt to correct the issue. After storming out of the Mainz Avis office, we decided to take the 30 minute train ride back to the Avis Frankfurt Hauptbahnhof because we still had our reservations from the day before, Thursday May 26 a.k.a. Corpus Christi. When we were picking up our reservation at Avis Frankfurt Hauptbahnhof, we were given another insincere apology about the holiday hours but at least they had our reserved car. But, it turns out that this location also had no baby seats! After showing the Avis customer service rep the confirmation email we received months ago that we reserved a car with a baby seat, a desperate move was made to ask the other car rental companies if they had a baby seat. Finally, Sixt saved the day and was willing to lend us one of their baby seats. After two nightmare days with Avis, we finally got what we wanted. What we've learned about Avis is that as an Avis customer, you are responsible for confirming all the details with your reservation location after you've made them online or over the phone. It is NOT Avis' job to confirm those details. You pay Avis your hard earned money, and they do NOTHING regarding your car rental reservation. This is your responsibility because they already made their money off you. We will never rent another car through Avis again and we will let our family, friends, and anyone on the internet looking at Avis customer reviews know what a horrible experience we had and we recommend that they rent their car somewhere else, like Sixt.
