I can’t even access the Instagram. how I set it up to 2FA if you block it?

I've been trying for ages now to get help with resetting the 2FA on my other Meta Horizon account on my quest 2. But I’ve just been going around in one big circle and unable to change the accounts 2FA settings in any way. Talking to AI instead of an actual person has not helped either. Is confusing you pay for the subscription you pay for this you pay for that to everything go against you it shouldn’t be allowed. I don’t have access to the Instagram no option to sort the problem. I’ll give a fishing solution to sort out the problem that they made a problem. Is so confusing!

Is there a real person I could speak to, to help fix my issue.

Thanks
