Dear Ms. Wu,
Thank you for your letter of 5 March.
We are always pleased to hear from a valued customer. I regret to say that we cannot agree to your request for technical information. As a matter of fact, our competitors also keep such information private and confidential. I sincerely hope that this does not inconvenience you in any way.
If there is any other way in which we can help, do not hesitate to contact us again.
Yours sincerely,
Tom Green
