Dear all I kindly ask you again about the book that was bought with the SEG creditcard on September 25 for Chf 33.25. Please try to remember and if you find the receipt please send it to me as soon as possible. I need it to pay the whole credit card bill. Thank you very much, I appreciate your help.
