Complaining Strategies for ConsumersWhen a consumer finds that an item she or he bought does not work or there is something wrong with it, what are the helpful strategies?The first thing is to present the warranty(保单),or any other records which might help, at the store of purchase. 26_______ However, if it does not, there are various means the consumer may use to gain satisfaction.27_______ In general, the " higher up" the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer' s favor, assuming he or she has a just claim.28_______ But if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter.Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. 29_______ For example, “The left speaker does not work at all and the sound coming out of the right one is unclear” is better than uThis stereo(立体声音响)does not work.”The store manager may advise the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and as firmly as possible. 30_______ She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumers' right.26.
