Weglot: AI & Human Translate

I have to say that I'm a tad disappointed with weglot. There's a few things that frustrate me. 1) the pricing. It's expensive compared with other similar apps 2) the support. Every month we seem to go over our word count. We've tried removing languages. But we've just launched a new theme and within days it says we're almost exceeding our translations. So something's not right? Support isn't very good at explaining. I'm thinking of looking elsewhere
