Failed to provide service, does nothing to rectify

I booked a Business class ticket for my girlfriend to travel from Pietermaritzburg to Midrand. Greyhound offers quite comfortable seats on their new Dreamliners. At the bus departure in Pietermaritzburg an ordinary bus arrived, not the Dreamliner that I paid extra for. No notice of this was received. The bus also arrived late in Midrand but I've gotten used to this with Greyhound. Greyhound did not contact me at all to apologise or discuss how they would be refunding my money. Once I contacted them they agreed to refund me the difference.<br> I feel a bus company that charges as much as they do should do more than that to make amends. Refunding me the difference is just giving me money that belongs to me. So they are really doing nothing to \make good".<br> My girlfriend would've opted for a later bus had she been notified when the bus left Durban for Pietermaritzburg."""
