I'm sorry . I've lost my tags and receipt . How can I do about it ?   I see . What is your baggage ? And do not remember the tag's number or color ?   It's a suitcase . But I've forgot the exact color . Maybe it is red or something .   Could you give me a description of your case ?   It's like this . It's square with a leather cover . Yes , I remember , there is a green string around the handle . That's right .
