Bad customer service

Been a loyal customer for Citybug Booked a ticket for my son I made a mistake with the date selection Instead of Monday I selected Sunday and paid everything online, Sunday 9am my son ask me why city bug sending him a text about leaving and I was like no way I booked for Monday

I checked the ticket and truly I made a mistake, quickly called them and explained my situation they said nope we can’t change u have to make a new booking and pay full price. They have many buses leaving to the same destination that are not fully booked they refused to put him on the next shuttle which was not fully booked because well “unfortunately we can’t help” People make mistake and it won’t hurt to be kind Never ever will I use them again
