copycat

Hello,an app of mine was copied by another developper.Not just the app features, but all the materials on the app store:- Same app name, they just added a plus word- Almost same description. All the special wording and marketing carefully created was copied with very little changes.I wrote apple but they said to report a copyright infringement. But it’s not a copyright or official issue is it ? I don’t care if they copy my app, I care of them using same name and marketing in app store.How to deal with the situation ? Is it allowed in the app store to just copy any app, use same name adding a plus or pro, using same app description ? Doesn’t Apple disallow blatant copies of apps and app store materials ?The form apple asked me to fill is supposed to put me in contact with the copycat. But I don't care about that and expected App store authority to prevent such behavior. Please advise
