Thanks for your post @fngIng and welcome to our Community Forums.
I'm afraid that we can't change the name of a mobile account, due to the credit checks we'd go through when you sign up.
Is there a spelling mistake in the name we hold for you or have you changed your name via Deedpoll?
Feel free to private message me, if you prefer to discuss further in a non-public space.
