Assuming you really represent the "Morrocco Method" (with a misspelling of the word "Morocco", the country), I don't understand why you'd shoot your business in the foot w/an insincere response:
On the one hand, you apologized for not getting back to her sooner. But on the other, you said, "We're very disappointed you felt you didn't receive the correct response ....
