Estimados Sres.
Acabo de recibir la funda de palm solicitada. Aprovecho para felicitarles por el buen servicio que ofrecen, hoy en dí­a es difícil encontrar proveedores tan eficaces.
Un cordial saludo

Dear people at Melgar,
I just received the palm case that I had chosen. I take the opportunity to salute you for the great service that your company offers, today it is difficult to find providers so effective.
I send you my best regards.
