Just received a request from one of our customers to send them the "invoice"of their purchase.
We did, but our item is $19(This is the price they have paid) and the number they see on the Invoice confuses them, which is $15.2
Naturally, they have sent a message to us as “this is not the amount we have paid, we were paid $19”
Now, what should we (or they) do?
They need a document (or documents) to show all the costs.
