Hi all
I realy need your help for the following scenario.
I gave my interview on Aug 18,2011 and selected. they told me that they will send me an offer letter in a next week, but today is that last day of their specified time but i didn't receive any letter from their site. I wrote the following letter, could you please improve it. Thanks

Mr. Smith,
I appreciate the time you recently took to discuss with me the position you currently have open at xxx company . It was a pleasure speaking with you and meeting your very competent staff. I found each of my conversations extremely informative.
As you mentioned in our interview, you will send me an offer letter in a next week but I didnít receive any letter from your site so far, could you please send it to me so that I can manage my thing according to that
I am very interested in working for you and look forward to hearing from you. Please feel free to contact me at anytime if further information is needed. My cell phone number is (306) 209-2326. 
Thank you again for your time and consideration.
