Instagram account retrieval following hack

I am looking for someone to help me with the retrieval of a personal Instagram account that was hacked. I have already contacted Instagram's support service, but their help was unhelpful. I have one form of recovery info set up - a phone number - but without success. I need assistance from someone who has the skills and expertise to help me in this situation. If you think you are capable of doing so, please reach out and let's discuss a project plan.
