The OFT has told six debt management businesses and four cold-calling companies to stop using unsolicited and misleading calls to advertise their services or face formal enforcement action. Consumers had complained to the OFT that they had suffered cold-calling either without their prior consent or despite registering with the Telephone Preference Service. The OFT also found that most of the information given to consumers was potentially misleading or missed out facts about the purpose of the call and identity of the caller.
