Hi,
The chat plugin – that does not really prove anything. If I view your live demo and see a live chat, I expect the same feature to have it on my demo also. Even more, seing it’s connected to your XStore support makes me think that I can connect it to my support department also.
The currency switcher – I would need to install a compatible plugin (one that so far you have failed to mention) and I would need to pay someone to make it look exactly like your demo – the top menu I mean.
I am afraid that if you cannot customize my website with the support chat plugin and the currency plugin I will ask for a refund as this is the first time I am seing a demo theme have extra features than the ones actually provided without any notifications.
Let me know what you decide.
