Trouble with 2xp codes

I recently purchased two 10 packs of halo infinite 2xp on 01/08/21 and there are zero codes under the pull tabs. I also noticed that it said something about purchasing before the 31st of December 2020, the only reason I bought them was the get the 2xp so I hope I didn’t waste my money buying these. any help and or advise is appreciated.
