Sample Introductory Paragraphs

This is my favourite. I've been using this paragraph quite a bit recently! :
Firstly, I would offer my condolences about the news of your share price plummeting in the last few months. I do hope my account has not contributed too much to your company’s poor performance.

I used this paragraph after being accused of 'Stalling Tactics' after sending the letters:
With reference to your letter dated XX/XX/2009, I find it remarkable that you will not verify the alleged outstanding debt, but instead, accuse me of stalling tactics. If I owe your company anything, you will be able to supply the requested evidence and if you decline it is you who is stalling and I will owe your company nothing...

Used after the company said they would look into the matter:
Thank you for your letter dated xx/xx/2009 outlining your investigation into whether or not your claim is fraudulent, however I am claiming lawful validation of the debt as previously requested; proof of agency; (List items requested) and have requested them within 10 days.

Used after being phoned after the letters were sent:
An employee of yours, Christina Williams phoned me on 11 February 2009. I have sent you a number of letters, having written to you on the 05 January 2009, the 15 January 2009 and again on the 25 January 2009 requesting proof of agency, (List items requested...)

Final Paragraph for companies chasing after a tacit agreement in place:
Finally, should you not understand that a tacit agreement is lawfully binding, I suggest you contact your legal department. Should you or any of your colleagues continue to contact me via telephone I must warn you that this will now constitute 'harassment' and I may be forced to take further action under Section 1 of the Protection from Harassment Act 1997.
