I'm really but... you can never be sure if that seller is the one who reported you. even if they are, it doesn't matter. it will help you a lot more to contact support and ask what went wrong. they have re-initiated denied gigs in the past, so there is always a chance.
as far as I know, it is okay to use the models, images, and other creatives if you have the proper rights to do so! best to look into the fine print and see if your purchase comes with commercial rights and stuff.
best to contact CS for a case-specific answer though.
