Not the service promised

The bus arrived on time, But it was not the bus we were promised. We received a Stabus, there was no explanation of why we had to get on that specific bus instead of the actual liner that we had booked. The stuff threatened that if we didnt get on the bus we wouldnt get another bus and we wouldnt even receive our refunds. The bus was dirty, it had a really bad smell. it was stuff because it didnt have any air-conditioning and the seats were as hard as stone and was completely uncomformtable for the 7hr journey. The bus driver was hostile. We couldnt even charge our phones. No explanation just threats. Horrible service on the day.
