I am writing regarding my Instagram account with the username “neha_vocalist_85”. I have lost access to this account since August and I am no longer able to log in. The phone number linked to this account was 9569956***. I have not been able to recover the account, and I have not yet managed to complete the “Forgot password” or other recovery steps successfully. I kindly request your support to help me recover access to the account “neha_vocalist_85” and reset my password so that I can use my account again.
