“…The lack of specific structures of complaints makes the study of complaint complex since different acts can be involved in a complaint situation. In this chapter I have presented some of the influential structures of complaint discourse functions (Schaefer, 1982;Piotrowska, 1987;Olshtain and Weinbach, 1987;Newell andStutman, 1989, 1990;Trosborg, 1995;Murphy and Neu, 1996;Laforest, 2002;Chen et al, 2011) as well as those that have served to design the classification for the present study (Schaefer, 1982;Piotrowska, 1987;Trosborg, 1995;Laforest, 2002;Chen et al, 2011). The structures of complaint presented in this chapter should be seen as a starting point to examine learners' complaint discourse functions, and therefore, it might be expanded if required to capture the nature of the complaints.…”
