Technical Bug in Online Store

Hi, I decided to buy the 'Dark Delights Kitchen' Bonanza Pack, which is still displayed in my game as available for several hours. But when I click on the offer, I get an error message claiming this offer was not found. I tried on different devices, iOS and Android, with the same result. It looks like the online store ended the offer too early.  Tried contacting support already, but my case was closed with 'no solution available'. I really regret waiting until the last day to make my purchase. Is there any chance this pack will offered again, or at least its content? Sorry, I only have screenshots in German language.
