Instead of saying that it's not the right format, the same thing was saying that you must have already activated it, right, because where I got this key, that's where the keys are usually given, now whether or not it's a scam on your part so I can tell you pay because it won't happen. Instead, contact the game developer itself, however if they say that the key format is not correct, I ask them to provide more information about the key formats as there is not just one format in the Steam market, now please after the keys having been delivered and activated as the coast in the photo posted, the subject no longer occurs to me, if you want money I advise you to look for a job suitable for your needs as there is no shortage of work.
