A BEAUTY clinic was yesterday branded for cheating and intimidating its customers into undergoing expensive and unwanted treatments. The Glory Beauty Centre was singled out by the Consumer Council as a ''delinquent trader'' after investigation into 12 complaints by customers. One woman told the Consumer Council she had gone to the centre for treatment to increase the size of her breasts and had been quoted a price of $6,500. After paying by credit card, she was told that an additional fee of $15,000 was necessary for the ''salinated bags'' to facilitate the enlargement. Because of the limit on her credit card she was only able to pay part of the amount and returned the next day with the $4,800 balance in cash. In the course of a physical examination, she was told her breasts lacked ''certain tissues'' and an extra $15,000 was required. If she did not pay, the earlier payments would be forfeited. ''In the embarrassing situation of having undressed for the examination, the complainant felt compelled to submit, albeit reluctantly to such an unreasonable demand,'' a Consumer Council statement said. ''The threatening tactic did not end there. Demands were made for the complainant to pay for various additional charges, bringing the final total amount to $42,800.'' The woman was also forced to sign and finger-print a debit note for $4,900, the Consumer Council said. Another woman said she had gone to the centre for an $800 treatment to have a mole removed, but ended up paying $31,600 for services she had not wanted. She was persuaded to make three payments by credit card for treatments against dark eye bags and to protect sensitive skin, as well as buying skin care products. Despite intervention by the Consumer Council, the centre refused to offer any refund to the women and the cases have been referred to the police. The company operates three centres. Two are in Causeway Bay - one in Cameron Commercial Centre, Hennessy Road, and one in the Capitol Centre in Jardine's Bazaar. They were closed yesterday. The other is in San Fung Avenue, Sheung Shui. Staff at the Sheung Shui branch also said business was closed for the day. They said the branches in Causeway Bay were closed for redecoration but would reopen in two days' time. The chairman of the Consumer Council's Trade Practices Committee, Justein Wong Chun, said: ''They [dishonest traders] usually offered a very low-cost service and product to attract consumers. And then they asked consumers to buy other more expensive products or services in the process of service. ''The consumers should stick to what they wanted in first place and try not to change their minds during the course of receiving services.'' He also emphasised that surgical operations could not legally be done in such beauty parlours. The Consumer Council received 67 complaints against beauty care centres this year. It received 90 complaints last year and 183 in 1991. The council also put three vendors of electrical appliances on its list of ''delinquent'' traders after receiving 35 complaints against them. They are Amigo Photo and Audio Supplies in Chungking Mansions, Nathan Road; the Hankyu Camera and Audio Co alsoin Nathan Road, Tsim Sha Tsui; and Fu Yu Electrical Shop (also known as the Direct Sales Centre) in Hoi Pa Street, Tsuen Wan.
