Missing adventure progress and card back

Hello, I wasn’t playing the game for some time and I’ve recently decided to play it again. But ever since I decided to play the game again, I’ve noticed that I have missing progress in a solo adventure “Frozen Throne” and a missing card back, the one that they gave away with the Samsung Galaxy promotion. After contacting support via mail and getting the same useless “solutions” I was redirected to post a thread here.
