It's been 4 weeks that support they say are working hard on my .doc document to make the dual taxes work correctly on my custom form. They say they are working on it with the team and then suddenly they ask me for screenshots of how I do it.

They have NO IDEA how this feature work.

And I can BET 100 bucks right now that they are not able to make it work with dual taxes in the Invoice summary.

Their support is the worse things I've seen in years.

Just after my post you'll see one of their bots post an article how to do this from Import Styles. As if I have not read this article. And they'll tell me that they really caring about my case, and to call support. And the bots are so much bots that they will say they are not bots.

But NONE of them bots will REALLY test the feature,

It does not work. People tell you all the time. You should just remove the feature. Stop selling something you cannot deliver.

Stop developing bots to tell us it works. 

Just fix the freaking thing.
