Xmas trip dister as first time customers

Worst trip of my entire life . Bus got changed last minute to a cheap bus . And im pregnant . My knees were blue because of the small seats bt i paid for greyhound bus trip . I want my money back . How can you make a pregnant women endure such pain for 12 hours on xmas eve from bellville to welkom on a packed non recline seat bus . What the heck and recieved no apology jst an sms to say ur bus got changed. People were drinking alcohol on a crowded bus . How was i forced to squeese thru the tiny isle at each stop .
