EA HELP are usually pretty good at restoring lost conent but there is a longstanding bug called the restore purchases bug that appears whenever you enter the store.
This bug seems to lurk in the servers and reappears after a reinstall but eventually goes away of it's own accord.
If you really haven't received something like a premium plant (easily verified) then i suggest you get onto them again.
As i said, they are usually pretty good with missing content cases and if you can prove you bought something and didn't receive it then then they will add it to your account then send you an email telling you so, sometimes with some gems or something as a goodwill gesture.
They have never restores my content. And sad to say, I've spent thousands of dollars on pvz2 they act like they could care less about their customers and their missing content. They are always unhelpful when I reach out. I love the game but I'm done playing unless they give me my hundreds of dollars worth of missing content
