Wargaming Customer Support Unreachable for Account and Email Erasure Issues

Even though I deleted my old World of Tanks account, the Gmail address linked to it still shows as registered in the system. Because of this issue that I discovered today, I am unable to use that same email address for a new account and am struggling to manage my account.

I tried reaching out to the Wargaming support team, but I was unable to get in touch with customer service through any channel. I want my account completely deleted and my Gmail address removed from your systems so I can freely use this email address again.

I request your help in reviewing this issue, completely unlinking my email address from the deleted account, and applying the necessary correction.
