It is sad to hear that you were harassed in dungeon. There is a report function but I feel in general it is useless and a waste of time as I don't feel SE does any thing other than the worst cases. Given you have played 30 days and still a green leaf, I would recommend finding other new players to join with. Join an FC if you can that has helpful players that are experienced and don't mind going into a dungeon with you and wiping a few times and help teach you on healing in FFXIV and getting a sense of different tank pulls. What to expect. Last if you are on a PS4, get a keyboard to help chat with party members , it will more often than not help resolve issues and keep things moving. In the end I would say stick with FFXIV as it is a great game even though duty finder can sometimes be very rough.
