They didn't have the correct car for me even though I reserved ~2 months ahead of time. Then, they gave me a smaller car and tried to convince me it was an upgrade. The attendant clearly had no interest in making me happy, she only wanted to get me out of there. When I pointed out that there were vehicles there that would be a true upgrade, she said that they couldn't release those because they were "reserved". I pointed out that I also had a car "reserved" and she couldn't provide me that vehicle, so why were the other reservations "real" while mine didn't really matter? Our luggage didn't fit in the vehicle provided, so we stayed an extra day before driving to our final destination so I could take the chance and try to swap the vehicle the next day. Phone support was also weak, with Alamo support having closed at 7:00pm and anyone else available said they had no power to do anything. Also tried Priceline customer support, they also claimed there was nothing to do, stating they only provide the reservation, not the car. Will never use Alamo, Priceline or Kayak again to get a rental car.
