Worst Cruise I ever been on

This was the worst cruise I have ever been on and I have been on several.  The ship itself was beautiful. Most of the staff was friendly but some made it se like you were bothering them. Our stateroom attend entered our room a very short time after we got on the ship and our luggage was delivered to our cabinet and unpacked. We were not sure why he was in our room so early into the  cruise as it was too early to turn down the beds and we had only been on the ship maybe 2 hours. Also every thing me we saw him working he was on his phone on personal calls the whole thing me we were on the ship. Very unprofessional. The first night I purchased a Spa treatment for that evening and one for the next morning.  After receiving myseaweed wrap massage treatment I awoke at about 3 am with my skin on fire and huge red rash all over my chest and neck. At 7:30 - 8 am I contacted the spa and told them if my reaction and that I needed to cancel my other appointment because my doctor advised me not to get any other treatments. I was met with the reply that I could not have possible had a reaction to their treatment, that it was too bad I still needed to pay for the treatment I was not allowed to have by my doctor. I went to guest services and after a long debate the called the spa and got them to not charge me for the service I was canceling due to my allegorical reaction. Not once was I offered any type of treatment , luckily I carry my own epi- pen and medicine because I am hypersensitive to many things. The Spa manager was very rude and in caring and did not offer anything back due to the failed treatment. I even contacted Carnival when I returned home, they offered me nothing for my bad treatment on their ship except the phone number to the Spa owner who still has yet to return my call.  By the third day of the cruise I was over it and ready to return home but I had 5 more days to go.  During my trip me on the ship I saw other people experiencing other negative treatment on the ship. One lady had a disagreement with her mate and was severely manhandled by security in front of the other guess. I don't see myself taking another Cruise on Carnival Cruise line because they don't seem to value their customers. If you want a good cruise try another cruise line.
