The story with Costa started badly from the beginning. It was our first cruise.
When we were getting on the cruise, we were attended by a person who barked at us in an incomprehensible language and forbade us to enter because of a non-existent schedule problem. Behind him came an officer on board who, in very bad manners, let us reluctantly pass by the cruiser.
On entering, we asked for the Wi-Fi in the Hospitality Service and we were 'greeted' by an Italian woman with very bad manners who made us feel like idiots for asking questions (it's her job to answer them, after all), and informed us that the Wi-Fi service was not only paid, but it was also divided into two RIDICULOUS categories: social networks and internet. Either you paid one or you paid the other. And they charged you 100 euros for 3 GB for the internet. The worst thing was that in addition to the theft of the price if you left the cell phone turned on unused it consumed all the data bought. Of course, this was not advised when offering the "service". We happened to buy the internet and went to dinner and on returning, we no longer had access because the data had been magically consumed.
