Changing FT user name

Hi , recently my FT account has been hacked , they asked me to create a new one, which I did under the username ‘’ JonR22R ’’
FT transfered my T$ and FT point to my new account and at the same time changed my username to my old one which is ‘’ DreamWorld84 ’’

Can you please change my FT username to DreamWorld84,
I can provide the e-mail FT sent me,
