I should have said more, sorry, I did tag them per category with the testimonials category. Now they do show on the testimony front page widget (great!), but – even after I “excluded” that category in the blog options, they are still showing on the blog page (weird). The blog options to exclude is not working.
The phone icon would be fine if it was one, here is the closest thing to a simlar square phone icon like the email icon – fa-phone-square  I have no idea where to replace that in the CSS code though. Thank you for the quick response.
