Schools and NGOs have become the latest target of unscrupulous salespeople who demand payment for stationery that was not ordered. In one case reported to the Consumer Council this year, a HK$500 ink cartridge was delivered after a salesperson called a school clerk claiming the school had placed an order. The clerk believed what she was told and stamped the receipt with a school chop when the cartridge was delivered. When it realised it had not placed an order, the school later tried to contact the salesperson to take back the product. But the company ignored the request and sent a bill demanding the school settle the payment, as it had acknowledged receiving the cartridge, or face further action. A teacher in charge of purchasing eventually paid out of his own pocket to settle the dispute. The council's chief executive, Connie Lau Yin-hing, said most victims in such cases in the past were big companies. In another case reported this year, one company was tricked into paying HK$43,000 for A4 paper that it did not order. 'But we found schools and non-government organisations are also being targeted this year. We have already informed the Education Bureau to remind all schools to be careful when receiving phone calls claiming they have ordered stationery products,' she said. In the first 10 months of the year the council received 32 complaints - two cases involving schools and one an NGO. There were 36 complaints last year. Ms Lau said the council had difficulty handling cases of this kind as it dealt mostly with complaints involving a company and a consumer. 'But this is about complaints involving two companies or a company and a school or an organisation. We can only do mediation between the two parties,' she said. The council reminded schools and organisations to strengthen internal communication and make sure staff members had ordered products before signing any receipts. 'Schools and organisations can also seek help from the police if a company keeps delivering products which have not been ordered,' Ms Lau said.
