Why are they all so weird.
I send an invoice to Gupta.
He replies that the PO number is wrong and he can't pay it.
I check and find the PO number is right.
I send him a copy of the contract with the PO number clearly marked on it
He says that PO number belongs to a different supplier
I tell him that he can clearly
see that it is my name
, my contract
and my PO number
No, says he. You are wrong.
I may have to phone him
