thank you for your letter of 23 december 2019.
we are extremely sorry to hear that a mistake has been made in your company's entry in this year's edition of the hotel trades directory.
the fact that two digits of your phone number were transposed must be causing you a good deal of inconvenience.i have checked with my editor and she confirms that we made the mistake.we offer our sincerest apologies for the trouble we have caused.
in mitigation,we did send you a proof copy of your entry before going to press.this was returned to us,signed by your secretary as being correct in every detail.had the error been spotted at that point,we would have made the necessary correction before publication.
in a directory of 300 pages,there are bound to be a few errors.the one in your entry is among three which have been reported to us.we have now instituted a new proof-checking procedure which should lead to an error-free edition next year.
we hope that you will continue to advertise in our directory.as a token of our goodwill,we are prepared to give you a 20% discount for your next entry.
