Urgent Instagram Recovery Assistance Needed

My Instagram account has been hacked and I am in desperate need of help. I have tried all possible recovery methods including Instagram's account recovery process, contacting Instagram support and changing linked email or phone number but to no avail. Unfortunately, I no longer have access to the email or phone number associated with the account.

- Key Requirements:
- Expertise in social media account recovery, particularly Instagram.
- Proven track record of successful account recovery.
- Ability to provide alternative recovery methods.
- Strong communication skills to liaise with Instagram support on my behalf.
- Confidentiality and trustworthiness are paramount.

Time is of the essence. I need this resolved as soon as possible.
