Twisp edge major disappointment not working

Bought my Twisp just over a week ago. The edge after two days only gives smoke occasionally , so I replaced the coil and the same thing happens. When I took it in and asked for a refund I was refused and was told they can only refund half my money. Which is not right because it's not my fault the product is not working. <br> So after some time they told me the atomizer is the problem can they replace it and see if that's the problem.<br> Guess what two days later no smoke again. But here is the best part I smoked my Twisp on the lowest setting. And what is really annoying I have only gotten liquid in my mouth for the last day.<br> I want my money back because this is not what was promised when I bought this product.
