Hi Patrick,
I compared with the demo font and the font used in your website. But i don’t see much difference there. You can check this video. https://www.awesomescreenshot.com/video/390819?key=21461189ad141b76ec25fa5b16e67e62
However, though you are using regular font variation, heading tags by default using bold font weight. So the font is bold in your website. You can remove font weight for those heading if you want. For that you can use this css to force them not to make it bold.
h1, h2, h3, h4, h5{font-weight:normal !important;}
Regarding the payment, i checked our account but there is not double payment from this email. p######k@c#########n.com.au. Can you please check your statement if you are charged twice for it ?
