Century Games Whiteout Survival Leadership Transfer Issue

As player 23070022 in Century Games' Whiteout Survival, I transferred alliance leadership to player 21448027 due to a confusion on Server 135. However, I've been unable to reach them since. Despite my attempts as the R4, they are not responding to any messages. I've shared the necessary screenshots within the game, but still haven't received any response from your end. I kindly request your assistance in transferring leadership back to any R4 member of the alliance. It's crucial for the smooth functioning of our alliance, and I hope for a swift resolution to this matter.
