Bulgaria’s Commission for Consumer Protection (CCP) has filed class action law suits against the country’s three mobile operators, M-Tel, Globul and Vivacom, for aggressive commercial practices. The cellcos are accused of sending ‘persistent and unsolicited’ communications to customers regarding the telephone game ‘Become a millionaire’. Customers were led to believe that their participation was free, whilst they were in fact billed for playing. SMS messages sent to customers also suggested that they had already been shortlisted to receive winnings and would only need to call or reply to the message. The CCP claims that the operators and the organisers of the game ‘misled consumers, concealed material information relating to the game and ways to refuse to participate.’ The watchdog said that it received more than 260 complaints about the game, referring either to the deception over charging or the persistence of the messages.
