AWS, lost MFA and a new phone number

Hello!

I am using MFA in my root account in AWS but I've changed my phone number and device before deactivating the MFA validation.

I am f*_!ed! I've called AWS support and they asked me to send a document which requires notarial validation so I have to go to the EEUU embassy and pay about 100$.

My personal account is costing me 1.5$ per month. A couple of domains which I don't care to lose.

Anyone with a similar situation? Do I really have to go to the embassy? It's possible to validate my identity in any other way? Maybe by the pay method?

Thanks in advance!
