Reset email password – Ask Different

My friend got me a new iPhone
We put the 2 side phones together to start transferring before this I had to change my iCloud password as I forgot it so did that
I really thought it was complete so I deleted everything from my old iPhone and left
I soon realised it hadn’t finishing transferring and it locked me out I filled the form and went through everything they told me do
They said they would send the code to unlock me to my email, I then forgot my email password, iPhone have told me they can’t help me till I unlock my email, I have filled out the form they ask u two about 10 time giving all actruate information an they keep saying they don’t recognise me, I have had the same email address for 10 years or more, I need my phone for work as I’m a Carer olease can you help me
