leaking areo device and refund

Between 21 May and 5 June I spent R6488 and Twisp Canal Walk to upgrade to their new Aero device. I am not going to complaint about the inaccurate sales pitch now. The coils last a few days at most, but the big problem is the devices leaks badly. I took the devices back 5 times and purchased two larger atomizers in an attempt to solve the problem. Every time I went back I was told to dry the atomizer (and loose more liquid). At the 5th return the salesman admitted that there is a problem with the design and that they are inundated by complaints (as this website confirms). On 27 June I returned the devices for a refund. I have not had the courtesy of a call or any feedback on my refund. Twisp is knowingly selling a defective product and expect customers to live with the consequences. I am awaiting a full refund, or the Consumer Protection Commissioner will have to be informed of the business practices of Twisp. I am since been very happy with the new devices I purchased from VapeMob.
