Greyhound San Diego Tucson recent customer reviews

I understand that the ticket was nonrefundable, but the company should've been able to work with me as far as allowing me to catch the next bus and also very ridiculous because I was at the station earlier just to be told I couldn't catch the bus due to only having $137 on card and need 138.99 on card and they couldn't accept the $2 extra dollars in cash
