I bought some tongs / hair wand from a business sellor. They come in different sizes so bought two the problem I have is I have another more expensive set that curls the hair alot better and gets hotter than these. I emailed the sellor to let him know they were not very good and that I wanted a refund. He emailed back they would accept them back but if they found no fault they would be returned to me no refund. They don't work as well as the other pair. Is there anything else I can do what are my rights?
