I just want my money back

Okay I really don't want to make this long and go into alot detail To make a long story short I am on my fifth cloud nine in only 10 months the fifth one is broken at the moment. I personally went to their head office to ask if I can have my money back as I am very dissatisfied with the inconvenience of returning the product each time. I was told that they know there's a problem with the recent batch from Korea but they're trying to collect all faulty ones and send it back but what they can do is offer me a Wella iron if this one broke. I was also worried about the warranty as I was told that I don't have to register the ones after the original one and that the warranty goes on with the first serial number I registered with. I really just want my money back cause this is a major waste of time and a very big inconvenience. I had high hopes with this product but Sadly I I'm very disappointed I hardly got to use it in the time that I owned all 5 of them I only got to use each of the about 3 or 4 times.
