Dear {Salutation} {Last Name}:

Recently I contacted your office.  I was assured that someone would contact me in a few days to apprise me of the situation.  After two weeks had passed without any reply, I tried again, with the same result; no return call or letter.   This has put our relationship on very tenuous ground after many years of doing business together.

Please reply as soon as you receive this letter.  I know you do not condone poor business practices, and I'm sure this situation can be easily corrected.  Thank you for your personal attention to this matter.

Sincerely,
