I had 2 issues when attempting to buy packs from the store with credits. First 3 of the 10 pack bundles I purchased did not award me with the mythic bonus pack. Second I was inly trying to buy 1 of the modern horizons 3 pack bundles but after attempting the transaction and hitting claim nothing showed up in my inventory nor did my credits reduce, so I tried again, and again nothing showed up, then upon restarting my game it had taken the credits for both attempts. I have not opened the 2nd second of packs as I was not trying to buy 20 packs nor pay 20k credits. These two are included in the 3 packs I was not awarded my mythic bonus pack as well so if I am able to be refund for one the duplicate purchase then I would only be short 2 of them as the other is from the lord of the rings pack bundle I purchased and did not get awarded the bonus pack. These purchases were done via the android mobile app.
