Dear Mr. / Ms, Thank you for your letter informing us of Mr. Green’s visit during June 2-7. Unfortunately, Mr. Edwards, our manager, is now in Cairo and will not be back until the second half of June.
He would, however, be pleased to see Mr. Green any time after his return.
We look forward to hearing from you.
Yours faithfully,
