Support unwilling to convert Mac software license to web
I've finished my taxes on the web, after ordering a Premier license (download) from Costco, and support is telling me they're unable (unwilling) to convert my license so I can complete filing online. I've had no issues in the past with getting DVD licenses converted to digital downloads, so it's mind-boggling why they won't help me here--some analogy related to ignorant/apathetic left and right hands seems applicable.
Has anyone been able to do this kind of swap successfully before? I know Intuit doesn't care if they lose me as a customer, but I'm not going to pay good money for terrible support.
