Can't Access Instagram Account, No Security Code Received

I can't access my Instagram account because the security code is not being sent to my phone number. I tried using the selfie help option, but nobody responded. Although my Gmail address is confirmed, the code is being sent to a different address. None of the options provided are working, and I'm being redirected to irrelevant places. Please provide urgent assistance. One thing I could try is to contact Instagram's support team directly through their Help Center, which I did. I explained the situation and provided all the necessary information to verify my account, what else can I do??
