There was a glitch preventing the "modify trip" from showing up, it took me 3 hours to connect with a real human after going in circles on all help forums and receiving texts instead of calls, what was advertised as a 180$ trip ended up coming out to way more, some of which is doubled on the receipt although I'm not being charged the full amount? They also triple-charged my account before returning the money. All in all, I respect the aims of the company but the service charges for hollow customer service are audaciously high and the company is not well-run enough.
