I got the following email.
Hi Talmid Chuchem :
Thank you very much for your purchase, because of my operational errors, you purchase the discount code set the wrong order, I am sorry to say to you sincerely. Because of this mistake, I will probably lose my job, but there are three children in my family who need the money I earn from work. I can not do without work. The boss says that as long as you can cancel the order and recover the losses, I can continue to work here. Can you cancel order?
I will personally compensate you a dollar to you, in order to express sincere apology. After my company there are many new products will have such a discount,I will send a mail to you, the first time you can easily buy the most favorable new products.
Look forward to your understanding and support! thank you very much!
