Viper SUP 104

So I purchased one of these from me adds and the fin was not with it. I thought it was supposed to come with one but am unsure. Any help would be appreciated. I attempted to reach viper customer service and now a week later have heard nothing. I hate to have menaces open another box to check (which they are more then willing to do)

Here’s the owners manual

Yes, a fin should have come with it.
