Ofcom pledges to protect broadband customers
The regulator made the pledge after instructing TalkTalk and Tiscali UK to cease charging people for services they were no longer receiving, or risk facing enforcement action.
According to Ofcom, the two bundle providers - which are both part of the TalkTalk Group - have generated more than 1,000 complaints in 2010 from billing subscribers who had cancelled their contracts.
The companies have until December 2nd to comply with the rules or face further action, such as a fine of ten per cent of relevant turnover.
Director of consumer affairs at the organisation Claudio Pollack commented: "Ofcom is determined to stand up for consumers and take action against companies that break the rules."
Last month, Ofcom revealed that consumers who have switched their services to another provider are owed millions of pounds by their former communications companies.
Britons have been left at least £10 million out of pocket over the past two years as a result of this practice, the body claimed.
