Dear Sumrit,
checking your account I found that unfortunately 3 invoices are still open which are overdue.
Attached please find our statement of account. Please arrange the payment of these 3 invoices within this week.
As informed by Mr.Valenta several times before, we will have to switch to advance payment if the agreed payment term 30 days does not work.
Please send us the remittance copy to proceed with the new order, else please inform if you are going to pay this one in advance, so I can prepare a proforma invoice for arranging the transfer.
Thank you for your understanding and confirmation by return.
