去年六月底,自称是北京钻凿技术有限公司业务员的吴女士,到唐先生所在单位推销旧空调,并声称该公司现有一批日产三菱重工旧空调出售。吴女士的推销能力使唐先生决定随其到门市看样品,之后也未发现样机有问题,遂即与吴女士签订了一书面协议,以2500元的价格选购三菱重工分体 At the end of June last year, Ms. Wu, who described herself as a salesperson of Beijing Drilling Technology Co., Ltd., went to the unit where Mr. Tang sold the old air conditioners and claimed that the company had a number of Nissan heavy-duty old air conditioners sold. Ms. Wu’s sales ability enabled Mr. Tang to decide to follow him to the store to see samples. After that, he did not find any problem with the prototype. He immediately signed a written agreement with Ms. Wu and purchased a Mitsubishi Heavy Industries division for RMB 2,500.
