Dear,
The service he used includes two stops, Taormina and Castelmola.
We gave everyone the opportunity to do both legs with a single ticket costing €20 for the whole day, not just for the outward journey. Customers boarded in order of arrival in Taormina, and were all taken to Castelmola and the port in time to be on the ship at 4pm.
We are sorry for what happened. We hope to see you again on board our buses.
