Greyhound Bus Service

Appalling bus service, the worst bus ever. We took a trip on 22/05/2023, the bus was 3 hours late without sending any notification. We paid for Premium Bus but we got a bus that had no aircon, it was freezing and dirty. I'm still waiting for a refund for the double booking that I'm being sent from pillar to post. Lisa Van Staden and Pamela Kaunda do not know what service means obviously as I've sent numerous emails with documents. They are simply the worst. Where do we complain about services paid for but not received? this is a ****, reminds me of Road Link...
