Problems accessing my account with security codes.

I have two accounts [removed for privacy] and [removed for privacy].

I now have no access to the latter email address as your security codes never work.

When I go to sign in to the 'art' email account it asks me for a security code, it tells me it is sending one to my phone, but it doesn't send anything to my phone. So, I request it to be sent to my alternative account [removed for privacy]

The security code arrives at my account, it worked once... and now when I go to sign in again it asks once more for a security code. BUT now they don't work.

The stupid site then suggests updating security details. And do you realise  what is stupid about this? It asks once again for a security code for access to security details. And guess what? The codes you send do not work.

I now have no access to a very important email account. I also have no access to my security details. I am sure that you must realise that somewhere along the line, that the account holder not having access to their own details and security is probably against data protection.

So I need this sorting and I need it sorting out fast.

Thanks.
