TalkTalk has been reprimanded by the Advertising Standards Authority about complaints related to its broadband advertising.
Issues were raised by BT about an advert for the firm's home phone and broadband (Essentials) package, which compared the TalkTalk service offered to a similar option from BT.
The company however failed to offer a completely correct comparison, with BT claiming two issues were potentially misleading as customers would lose broadband security features by switching.
The advertisement stated: "You could make great savings with our new myTalkTalk home phone and broadband package ... plus you could save up to £112 a year compared to equivalent BT products."
According to the ASA, the complaints were upheld as the advert breached CAP Code on a number of clauses and the organisation demanded it should not be broadcast again in its current form.
TalkTalk recently worked with students from Goldsmiths at the University of London to design the broadband router of the future.
