The Advertising Complaints Committee (ACC) has upheld nine complaints about adverts.
Among the adverts objected to was a radio commercial for Jurys Inn. It said: "Cork and its countryside, Galway on the bay, Limerick near the Burren...or is Belfast on your way?....Enjoy up-to-the-minute comfort from just €49 per room for three adults or two adults and two children sharing."
However, a person who wished to book a room in the Galway Jurys Inn was told that the €49 rate only applied to certain hotels, and that the Galway Jurys Inn rate started at €69.
Two newspapers were found to have breached the Codes of Advertising Standards.
The ACC found that a Sunday World "Free Prize Bond inside" advertisement was not for a free prize bond but a lease of a prize bond for one year only. The committee also upheld complaints about television and press advertising for a free Carry On DVD in the News of the World. One reader bought the paper and discovered that there was no DVD.
Other companies against whom complaints were upheld include: Esat BT, Dell Computers, Xtra-vision, Spy Security Systems and Sky Television.
