Unable to Recover My Instagram Account Despite Submitting an Appeal

I am having a serious problem accessing my Instagram account with the username @Sivnya447. When I try to log in, I constantly receive an “incorrect password” warning and I cannot enter my account. I have also lost access to both the email address and the phone number registered to this account, so I am unable to reset my password through the usual methods. I filled out the relevant Instagram help/appeal form about not being able to access my email or phone number, but despite this, my problem has not been resolved and I still cannot access my account. My clear request is that my account be recovered and that the email address or phone number registered to my account be changed to an address/number that I can currently access, so that I can log in securely again. I kindly request that my identity be verified through alternative methods if necessary and that my access problem be resolved as soon as possible.
