transfer game data problem

I recently became aware about the transfer game data with a konami id in order to not lose data after a reinstalling of the game or such but when I'm about to launch browser for data transfer set up, game warns: "if data transfer settings have already been made for this play data, they will be lost if you use another konami id for the transfer settings". I'll be honest, I don't remember if I already have a konami id and I'm afraid to lose my data. do you guys know if there's a way to verify if I already have one? and if not, what should I do? moreover, I'd like to know how I can contact konami directly by email. thanks in advance and forgive my ignorance in matter.
