Telegram complaint: Ignoring request to remove racism conent

@NSDAPchannels – this telegram channel is full of sub-channels with contents of racism, anti-Semitism and much more.
I send an email to [email protected] reporting an obvious anti-Semitism activity in this channel and in all its sub channels in Aug 2020, never got any respond. Sent a reminder – no respond.
On 12 December 2020 I sent a message to Telegram support in Telegram, so far – still no respond.
Meanwhile that channel is spreading a content that just can’t be supported by our modern society.
I don’t believe Telegram supports this kind of activities, therefore I asked them to shut down the activities of @NSDAPchannels on telegram platforms.
No action was taken.
My complaints is for ignoring my request to remove their contents. Being a Jewish,I am offended on personal level. Ignoring these kind of requests makes Telegram supporting that channels activity.
