For some reason, it was already paid through PayPal and the invoice is invalid. If possible, will you please send me an invoice again? Thank you very much.
I suppose it has already been paid with paypal but the invoice is invalid. Sorry to trouble you, but is it possible to resend me an invoice? Thank you for your consideration.
I didn’t pay by PayPal, but the system shows that I did for unexplained reason. So the requisition has become invalid. Would it be possible for you to send me the requisition again? Thank you for your consideration.
