Telegram ****

Someone hacked my Telegram account and is impersonating me on Telegram. The hacker is trying to get people that I know to invest in Ashburton investments on Telegram. Personally I think it's a ****. They changed my email on the telegram and now I cannot login or delete my account. I have sent atleast three messages to Telegram support to inform them what happened and requested to delete my account so that they can stop ****ming people. But I have not received any feedback.
