still waiting on a feedback after 3 weeks

About a month ago I purchase the new twisp Solo. Within 2 days I went back to the consultant and inform him that the product was coming out into my month as a smoke. He took down my details and I am still waiting on him to come back to me with feedback. Last week I mailed the customer service regarding the problems that I accrued with this product and that I was now experiencing a bitter taste with the new Solo. Now every time I fill the Solo with the liquid,it runs down and come out by the top. I am wasting more of the liquid than actually using it. It cost a lot of money (R200) to waste. I am not happy and very upset as I spend a lots of money on this product and no one even bother to email me regarding my concerns. Really Bad Customer Service.
