No method to contact customer service when there is a problem.
I had good experiences in the past, but this time the website booked my name incorrectly with the airlines. I had booked correctly before with a login, so I know my name is correct in their system. But it entered my name incorrectly when transmitting to the airlines this time. It resulted in change fees due to budgetair.com not having any phone number for customer service and no way to have them correct an error that they made.
The had to contact the airlines themselves to make the changes.
