Dear Mr Ahmadi, I am writing

this

letter to you to apologize, for my huge mistake which leads to the dissatisfaction of our old client.

Firstly

, I have to apologize to you, because my mistake about

this

happened had a significant impact on our situation. And create undesirable conditions to continue our cooperation. Actually, as you know, when we make a contract with fly butter company , they offered another date to deliver all products to them ,

however

, after more discussion, the date was set a few days earlier. But unfortunately, I thought the

first

deadline was correct. I completely agree that my mistake creates huge problems for our company and I promise after that I consider all dates of our contract and try to negotiate again to them and I hopefuls due to my relationship can consider a new deadline. Thank you for taking your time and your consideration of my letter. Yours sincerely, Salehi
