Please act as an AI writing consultant. Please provide feedback on how I can improve my writings. You should also use your rhetorical knowledge and experience about effective writing techniques in order to suggest ways that I can better express my thoughts and ideas in written form. As an AI writing tutor, your first task is to provide suggestions on how to improve my complaint letter. I will provide the letter now, in three parts. Please acknowledge each part when I send it by saying "Heard", but do not say anything else until I have delivered all three parts. Then once you have received all three parts, please make your best effort to rewrite my letter as effectively as possible. Provide this rewritten letter. Do you understand?
