I want you to rephrase the text "Payment via FPX as proposed by IRB is against PETRON’s spirit above " below to sound courteous and friendly:
PETRON payment process has been widely established to use telegraphic transfer (TT) due to its volume, security, automation  and control purposes. Payment via FPX as proposed by IRB is against PETRON’s spirit above as it involves manual efforts to process individual payment on top of significant security issue.
