Hi everyone, I am wondering if anyone has undergone the process of requesting a finalized copy of flight cost from Air Canada?
I have a reservation that I made a few changes and paid/refunded various fees/taxes/fares. At the end of day I need to submit an expense report to my company, but I'm left with multiple partial receipts which is hard to piece together the actual ticket cost to my company's accounting/audit department.

In my specific case, I bought YYZ-YVR ticket initially (receipt 1), then changed it to YYZ-SFO, which had refunded CA tax (receipt 2) and charged new US tax (receipt 3). I then changed fare family which resulted another charge (receipt 4). Receipt 2/3/4 are kind of vague on what exactly the charge/refund is, especially receipt 4 makes it look like the ticket only costs 200ish bucks.

I have tried using the custom care webform to request receipts but it just sent me those 4 receipts again, in an even harder to understand format. There is an option to request invoice from AC but the description says it's only for ticket sold outside of North America.
I'm wondering if anyone has experience obtaining the receipt/invoice for the whole/final itinerary, with the correct final price shown on it.
