disgrace of an app

This is very useless if I must say, I booked a bus with them the bus never showed went on bus bud they never cared or addressed the issue , i will never be recommending this site to anyone I know. I wanted a refund never got it the company Citi link said I needed to cancel and request refund with Bus bud since ticket was bought via their app, Bus bud never did anything the only message I got was my ticket is not refundable
