I did not get credits for my cards and packs

I saw someone start a new account without migrating and they had the same amount of credits and crystals I started with after migrating. I had plenty of extra cards and close to the max amount of unopened packs. They also got a free lugia deck and a couple of decks I didn't get. Idk what is going on but now I don't have enough stuff to build decks and have no way to get more credits or crystals in a reasonable amount of time. I got cheated just because I migrated right away without opening my account before migrating.
