I bought an item online which does not work satisfactorily. I have received a returns authorisation which gives me the options of repair or replacement, what I want is a full refund including the outward and return postage. Am I being unreasonable?? The item in question is a "soundfeeder" fm transmitter for my mp3 player. It doesn't transmit on all the stated frequencies, and is totally inefective at distances of more than 2/3 feet and even then physical contact must be maintained to ensure half decent sound. Can any one suggest how to achieve the desired result??
