I see where you are coming from but you cannot say that definitively. The wording could be a little misleading and no one can speculate how much was given
In the Distribution and Manufacturing industries, PO's are typically billed and paid in full unless there are backorders or separate shipments were requested (in which case each shipment is billed separately). Invoices are produced on shipment. There is nothing in the PR to indicate that it wasn't shipped/paid in full.
