I haven't even opened the packs as I knew that would have been a problem, you can take the packs back if you want but it wasn't my fault, I had completed the SBC before its expiry so I don't get why I shouldn't get the player back. I am sure there's some way you can check the progress I had in the SBC, I lost 1.5 million coins and pretty much my entire club to get my favourite player for which I had grinded the game for an entire month...
