Bought something I never clicked on(?)

[Papa Ribs]

Hey all! So I was looking to buy the Season Pass for BL2 and ended up getting it but my moronic self wasn't paying attention and there was a second item in the trade (Upgrade Pack 2 or whatever) and I'm seeing it now and realizing I ended up buying something that I never clicked on?? I knew ahead of time that the Season Pass had the aforementioned pack so I personally had no reason to buy it. Anyone else have this issue before?
Hoping it's possible to be refunded as I needed those keys for trading...
