The mask mandate is annoying but makes sense. We were on a Western Med. trip in May (on the Vision) with no mask mandate, and I came down with COVID. Someone in our party tested positive so we all had to test. I was put in a dingy, dirty cabin on Deck 3 for 7 days. I had to ask for basic medical supplies and put up with poor food service and no medical attention. While in quarantine, I received a letter stating that both my husband and I should receive a prorated refund for my time in quarantine within 30 days. For several weeks, I have been trying to get RCCL to do what the Vision letter promised. Now, RCCL says that they will only refund me and give my husband a future cruise credit. A FCC is not acceptable. After my treatment, I am not sure I want to cruise on RCCL again. Does anyone have any ideas about who I could contact or what I could do to rectify this situation? I am only asking for what was promised and now RCCL is changing its tune.
