I think your email is clearly worded, polite and respectful, but I feel the reason for it is disingenuous and more than a little unreasonable.
I suspect they will possibly do something for you here, but if I were you, I would refuse it and say upon consideration, you think mistakes occur and that they shouldn't be out of pocket for a genuine error but that you appreciate the gesture and will sing their praises for being willing to work with you anyway.
It was a genuine error on their part, you have said yourself you were dealt with professionally, and I think you are being opportunistic in pressing the matter.
If I were you and if I had been inclined to write the letter, I would have written upto "and I have copied him in accordingly."
I would have then stated something like "Whilst I am disappointed at being unable to secure such a good deal, I wanted to highlight xxx's excellent conduct", yours sincerely xxx
You might have gotten a $50 voucher out of that or something, which is absolutely all that would be reasonable.
Just my 2c worth.
A very fair and reasonable analysis of the situation, and good food for thought, thank you. I hadn't considered myself to be either disingenuous or opportunistic but on review, I can see how you would come to that conclusion. Perhaps on reflection, I was being some degree of of one or both, albeit unintentionally or at the very least, subconsciously.
I'll take your feedback on board and digest it a little further before taking any more action on the matter.
