According to Gillian Guy chief executive of Citizens Advice, "attractive headlines" prevent consumers for making an informed decision about what internet package is best for them.
“A broadband market that works for consumers should be competing on the overall cost of the available deals rather than on how difficult they can make it for people to work this out," she said.
“Broadband providers need to make the costs of a contract clear in their advertising and the Advertising Standards Authority should also review the code of practice to make sure it works well for consumers."
In November, the Government pledged to investigate whether internet service providers of home broadband are using teaser rates in adverts to hide the overall cost of contracts.
