Dear Mr. **,
I feel so sorry that my manager would be unable to perform your agreement of meeting on Friday. Please forgive us for he have got something urgent to Beijing.My manager also feels guilty for it and suggests If you would give us a chance, we hope to put off the meeting in next Monday. I must genuinely make an apology to you for my failure of keeping my promise again.
Yours,
***
