Daylight ******* by Greyhound

Please help me guys My husband booked a ticket ( from Pretoria) for my son who is in the Eastern Cape to go to Pretoria on Saturday. On the ticket there is no mention that we should also look for Greyhound buses. We waited until 8h30 for the bus which was supposed to arrive at 6h55. Now today when we enquired they told my hubby that a message was sent to my son's phone, and at this moment my son's phone is damaged. I was the one who kept calling the number on the ticket with no luck. Today Sunday they tell us they can't refund us, and we ask them for my son to board a bus today using the same ticket we bought they are refusing. Wow, this is daylight ******* from a company which claims to be in the business for a long long time. Is this how they treat their clients by robbing them. Explaining what we should have done instead of rectifying the problem. I'm so ****ed off right now.
