Dear Sirs,
Muy señores nuestros:
We have asked you repeatedly to settle your outstanding account for $3,750. Unfortunately we have received neither a reply from you nor your remittance.
Les hemos pedido repetidamente que salden su cuenta pendiente por 3.750$. Desgraciadamente, no hemos recibido ni una contestación ni el pago.
Unless we receive your payment by March 31, 19- we shall be compelled to place the matter in the hands of our lawyer. As such a step would damage your credit standing, we sincerely hope you will send us your check immediately.
A menos que recibamos el pago antes del 31 de marzo 19- nos veremos obligados a poner el asunto en manos de nuestro abogado. Como esto perjudicaría su solvencia, sinceramente esperamos que nos envíe el cheque inmediatamente.
Yours faithfully,
Atentamente:
