Lost Montblanc pen at QNB City center

I lost my montblanc pen at QNB City Center Branch Office on August 31, 2009 around 8 PM. There was a couple who borrowed my pen to fill in the form, but when my number was called I went to the cashier and unfortunatelly forgot to take my pen back from them. If this couple read this memo or anybody else knows about it, please respond to me here. The pen has a very sentimental value for me. Thank you
