GST not calculated and displayed in order summary

This plugin is not displaying shipping tax correctly. Enabling tax for shipping seems to add tax to the total, however its not displayed as GST on the order summary after the order has been placed (or in the admin area). This is terrible for clients who require an accurate tax invoice for purchases.

I sent an email via the “contact us” section of member area on the Transdirect website a week ago, and selected “Api / Plugin Inquiry”, however I haven’t heard anything back at all (not even an acknowledgement!).

Can I please get a reply here or in my original email about this issue?

This plugin seems to be terribly out of date, and not integrated into Woocommerce shipping zones, which I assume is why its not displaying tax rates correctly.
