Hi @Igor Sychev ,
I was able to find your name in the tenant and created a support request to have you removed. If you remember who added you and could share more details about your scenario, that would help me.
Feel free to reach out to me at AzCommunity@microsoft.com ("Attn: Marilee Turscak") to provide those.
I already have a support ticket opened for you which may be sufficient to get this resolved, but we may end up needing more information from you. Thank you,
Marilee
