High quality goods and service are always what we long for, however not all the time can we enjoy such high-level treatment.  Broken electronics, or inconsiderable hotel service, both annoy us and add our complaints. To demand for a fair and deserved  commodity or service, we have to complain to certain sections, either in writing or in conversation. People's preference divides  on this issue, and I prefer to talk to someone to address my problem. It is more direct, clearer, and helpful in persuasion.

Talking can be direct, and it is fast and clear. Considering the whole process, we have to present how the products fail or where  the service s annoy us in detail, plus we have to prove that it is not our fault that leads to this problem. Then we have to  negotiate to reach an agreement. This is like a bargain in the market--we have to emphasize our rights and what we deserve. No  one would like to waste long time to complain, but to reach satisfactory solution is not easy. Since the process of complaining involves with detailed fact, responsibility confirmation, and ultimate proposals, communicating in direct way could ensure enough ideas exchange between the two, and this could help us solve the problem. Face to face communication could add extra information like our tones, and emotions in the complaint. When we are angry and anxious to get our problem addressed, the counterpart would probably pay more attention to our demand. And if they realize the urgency of the issue and potential harms the bad products bring, they would act more rapidly in helping us handle the complaint.

Compared with complaining in person, writing is indirect way of communication, slow and inefficient. Mails, or e-mails is not  reliable for handling serious issues. Sometimes mails got lost or ignored by the receiver, even for the complaint department of  some company, not all the letters can be carefully read, and replied. Any delay in the process of mail could postpone the  complaint and may finally leave the issue in suspension. After all, we customers can not afford to pay too much time and energy  on  asking for complements.

To conclude from the above arguments, complaining in persons possess some superiority over complaining in writings, as  communicating face to face is direct. We can clarify the issue and handle it quickly. Compared with that, complaining in writing is unreliable and slow, somehow postponing the process. The direct communication can add more information like tones, emotions,  enhancing the chance to get the problem solved.

High quality goods and service are always what we long for, however not all the time can we enjoy such high-level treatment（倒装加分）.  Broken electronics, or（可删除或者改为and，因为后面用的是both） inconsiderable（是微不足道的意思,可以改为terrible或awful） hotel service, both annoy us and add our complaints. To demand for a fair and deserved  commodity or service(感觉不大对，没有人说一个fair的东西，我的话会改成To demand for a deserved service or a qualified commodity), we have to complain to certain sections(我的话会用point out problems), either in writing or in conversation. People's preference divides  on this issue, and I prefer to talk to someone to address my problem（感觉不太好，还是用complaint）. It is more direct, clearer, and helpful in persuasion（我查了一下，persuasion更多是一个劝说，但是complaint并不是劝说别人，"说服"的话用to convince，"表达"的话用in expression）.
Talking can be direct, and it is fast and clear. Considering the whole process, we have to present how （加上did，fail是动词）the products fail or where  the service s annoy us in detail(有点chinglish)（我请教了一个高手，他改成：we are committed to illustrate the reasons why products and services  are not  satisfactory as expected and deepen them to details as to how they annoy customers ）, plus we have to prove that it is not our fault that(which好点) leads to this problem. Then we have to  negotiate to reach an agreement. This is like bargaining in markets--we have to emphasize our rights and what we deserve. No  one would like to waste long time to complain, but to reach（reaching）a satisfactory solution is not easy.

Communicating in direct way could ensure enough ideas exchange between the two(不对，我也不知道怎么改，two sides 怎么样), and this could help us solve the problem.
