Excuse me . I bought the CD here two days ago . It's scratched , and doesn't play properly .   I'm sorry about that , sir . I'll get you another one .   The thing is I've replaced once already . I think it's just a faulty batch .   I see . Maybe I can offer you a credit note .   Well . To be honest , that's not much use to me . I'll leave the country tomorrow . I'd really prefer a refund .   OK , sir . I'll see what I can do .
