We regret to have to complain about late delivery of the pizza order on October 25, 2014. We did not receive them until this morning though you had guaranteed delivery within a week. It was on this understanding that we placed the order.
Unfortunately, there have been similar delays on several previous occasions and their increasing frequency in recent months compels us to say that business between us cannot be continued in conditions such as these.
We have felt it necessary to make our feelings known since we cannot give reliable delivery dates to our customers unless we can count on those given by our suppliers. We hope you will understand the position we are in and that from now on we can rely upon punctual completion of our orders. Thank you for your cooperation.
