Change Norton Internet Security to Norton Security Deluxe

I have Norton Internet Security which does not need renewing until November.

But the Norton Mobile Security on my phone has expired. 

I am thinking of changing to Norton Security Deluxe which would cover my three PCs and allow me to include another PC and the mobile phone.

Is there an actual EMail address / form where I can contact support, I hate using chat and don't want to phone.  So much easier to type out an EMail and get an answer to it
