Stressed with trying to be verified!

So apparently Amazon were unable to verify my documents. Therefore they sent a verification code to my house. Even after this, it’s still saying ‘I can’t sell and they can’t tell me why.’

If written to their customers and either get an auto response saying they can’t verified me, or now I have had a human respond and ask for more details on the issues I’m having…..but when I respond, I get an auto response saying the email I’m sending it to can’t accept incoming emails!!

So stressed over it, why is it so hard!!
