Major currency double conversion issues. Support unhelpful.

First of all, I already opened a support ticket, which I had noted in my last review. Second of all, the WordPress Support Moderator can’t seem to understand that a review of the product support and reliability is just as much a review of the product as a review of the functionality alone and had deleted my previous review. I detailed all the painful steps for future potential users to understand the risks of using this product, especially if they bite the bullet and pay for the Pro version, which I did to enable automatic exchange rates.

I have a product set to THB, while the rest of my store is in USD. The product displays THB correctly but then when a user is either logged in or enters any address (I tried both Thai and US addresses), it double converts to 113000+ THB, as if the 3500 THB were originally in USD. Support was barely responsive in 5 days, once only to confirm the bug and ask for access, a second time just to tell me my site was inaccessible when it was up. Meanwhile I’m losing sales, couldn’t close the product page because I was leaving it open for support to see the bug, and I had a customer email me frantically asking for a refund because they were horrified to have been charged the Thai baht equivalent of $3500 USD because they hadn’t noticed the double conversion. I refunded them, of course, but that transaction cost me a nonrefundable $188 in transactions fees to WooPayments.
