My Instagram Account Hacked. Recovery Request Ignored by Support

A while back, my account @c** got hacked by someone called @f**. They managed to get into my account and reset everything. After reaching out to Instagram officials through Gmail, they refused to acknowledge that the account was mine. I kindly ask Instagram to address the issue regarding the user @f** who gained unauthorized access to my account. I would greatly appreciate it if they could restore my @c** account to its original condition. Kindly proceed with the required actions promptly.
