I have two Telegram accounts on both my personal laptop and mobile device. Today, I noticed that one of my accounts was deleted, and the other account sent casino-related spam bot messages to all my contacts and groups. Surprisingly, both accounts had two-factor authentication (2FA) enabled.

Here’s the situation:

My deleted account was my main account, and it had a Telegram channel and group that I created five years ago. Since the account was deleted, I no longer have access to either the channel or the group. I can still see spam messages being pushed through both. When I re-entered my mobile number and previous username, they were available and working—but none of my past chats or data from the last five years were there. Is there any way to recover my channel and group?

As for my second Telegram account, it wasn’t deleted, but the same spam message was sent from it to all my friends and groups. What are the risks associated with this account? I’ve already changed the 2FA settings and Telegram password, and I’ve formatted my laptop as well.

If anyone can help me recover my group and channel, I would truly appreciate it—and I’m willing to offer payment for successful recovery. I’m not sure what to do next, but I’m hoping someone here might be able to help.
