I downloaded a game today and found, in the soundtrack, offensive language that wasn't declared in the app store description. Is this a case for the developer to deal with, Apple, or a solicitor, as it has traumatised my son?
Surely offensive lyrics didn't traumatize your son. If he didn't know what they meant, they were meaningless and not trauma inducing. If he knew what they meant, it was too late for them to induce trauma.
[MOD NOTE]
Enough with the snarky answers, the OP came here for help and all he's getting for the most part is sarcastic responses.
OP, the only think I can think of is to rate the app with a single start, or at least contact the developer. It might have been a simple oversight on his part.
