They say that I can get an invoice from their website, but the information does not include the transaction date and supplier ABN (which is a requirement as per https://www.ato.gov.au/businesses-and-organisations/gst-excise-and-indirect-taxes/gst/tax-invoices).
I need this because another company will reimburse the expense, and they (rightfully) require a TAX invoice as proof of purchase.
I've asked for the tax invoice via a support call two times. First, I was told to redirect my request to their support email address, but they don't reply. The second time, they confirmed they won't supply this, no matter what (I have the call recorded, with their permission)
What else I can do? What's the best way to report this to the ATO?
