Instagram Account Inaccessible Since 2017 And Needs Deletion

I am the rightful owner of the Instagram account with the username “Gloriieh”. I lost access to this account in October 2017 because it is linked to an old email address and phone number that I no longer use and cannot access anymore. For this reason, I can neither log in nor recover the account through the standard methods. Since then, I have tried several times to reach Instagram through the Help Center by filling out forms and explaining that I am willing to verify my identity, but I have not been able to get a solution or clear guidance. As I no longer have access to the old email and number, I also cannot receive any recovery codes. At this point, I no longer wish to use or recover the “Gloriieh” account and instead request that this old account be permanently deleted. I want to prevent any possible misuse or confusion, as the account is still publicly visible even though I cannot control it. For any necessary confirmation regarding this deletion request, I can be contacted via my current email address: glokarwi***@gmail.com. I kindly ask you to review my situation and ensure the permanent deletion of the “Gloriieh” account as soon as possible.
