Bitten by bed bugs and they didn't care

Cruised on the Star in March 2019 and ended up with bed bug bites on last day. We were very disappointed and frustrated by the lack of care, knowledge and thoughtfulness of the Guest Relations staff who responded to our case. These bites of course ruined our vacation, and we then had 2 extremely stressful weeks afterwards at home, worried we had brought bed bugs home with us (we slept in a tent, bought pesticides and bed bug traps, etc.). The initial response was basically, sorry this happened but we checked the room and it seems fine. I sent pictures of my arm to show that I wasn't dreaming this up. I wasn't covered in bites so there wasn't an infestation and a couple of bugs could easily hide, if the people who answered us knew anything about bed bugs. We've done a ton of research and know a bit now. They can hide in pockets and easily get transferred from one place to another, so if the Star has had any reports of bed bugs, then they could have ended up in our room. Because we were treated with such a lack of care, we are sad to say that we no longer want to sail with Norwegian and they were our favorite cruise line. All we were asking for was our Cruise Next deposit back and were refused any compensation for our trouble. This is not how you run a business and treat your customers. We have taken 4 cruises and spent at least $12,000 total with this company. We feel we deserve at least our deposit back minus what was credited to our onboard credit; this would total to $250. How much trouble would it be for Norwegian, that is worth billions of dollars, to give a customer a small $250 refund for a bad experience and ruined cruise? We tried to reopen our case and heard nothing from them.
