For logo in mobile view you have to follow “Header Logo Margin Setting” of Dashboard >> Appearance >> Customizer >> General configuration >> Header Logo Margin Setting >> Set margin as you want. For “services” section and “Online Training Programs” kindly check by hard refreshing site ( Ctrl + Shift + r ).
We have checked phone number is showing black in mobile view same as desktop view.

If you have any other issue then please let us know.

Thank You.
