I purchased the " Arena Req Pack" on 2/16/16, and I stopped receiving the packs last week. To be clear, I have not received the req packs for the last 2 weeks. I am not sure what information to include here as this problem might involve purchase info. My gamertag is Dreadnip, I will happily supply the order number or cc used, but not over a forum post.
Hi OP, if you bought the pack mid-february then the last of your bundle would have dropped around the 22nd of March (as you get 14 packs in total, 2 every week for 7 weeks)
