Instagram Login Error

Hi there, I'm facing a frustrating issue with my Instagram account. After entering my password, I'm prompted to enter a 6-digit login code, which I don't have. When I opt for an alternative method, it requests an 8-digit backup code. I've tried all the backup codes I recently purchased, one by one, but none of them are accepted. I've reached out to the support team and even sent a selfie as requested, but so far, there's been no response. I urgently need assistance with this problem. It's been quite frustrating and worrying.
