The text on the top can be changed only by click on and type.
Now in the header keep in mind you have only 3 rows in these 3 position you can add the top header (Question phone number, login), Main ROW(logo and the cart + whishlist), The bottom row (menu)
This is the configuration that you can make without any customization.
The controls were covering it. i edited the css responsible for it and moved the controls down a bit. You can now just click on the text to edit it out. I already tried it with the phone number in top-header.
Please clear cache and check.
