Massively overcharges for international shipping

Massively overcharges for international shipping. Their 1st tier support team could not solve the issue after many rounds of emails, and finally gave up; they pushed it to the next level of support. Then it took far too long for the next level support to get back to us (weeks). When they did, they asked us to collect some data on test orders, etc., basically the same set of data that we had already given them weeks ago.

Nevermind! Moved on to Shippo which handles the same international orders with no issues.
