Hey WimmaDodo,
That would depend on when those purchases were originally made as well as some other account specifics, so it's nothing I'd be able to determine or detail here on the forums I'm afraid.
When it comes to duplicate purchases, unfortunately no one on the forums would be able to assist. Anyone that had this issue in the past would have also needed to have support take a look since they'd be the ones able to make adjustments to certain purchases, depending on the situation. I would definitely recommend resuming the case from your case history page to speak with support again if you still had any concerns.
