Twisp : grab the money and run

I went to my usual Twisp kiosk in Tokai Mall. I wanted to purchase the MiniVega. The Twisp seller convinced me to buy the latest Tank, the Arcos. It costs a whopping R 600 to add to the price of the other parts for a smoking alternative. The first time I wanted to change the Coil (after only 1 day) the Tank *****ing system jammed and I was not able to access the Coil to replace it. The Twisp seller then tried to un***** it himself to no avail. He wanted to replace it with a new one. I did not want this as I was convinced that I would get stuck again with a jammed tank. So I was given no alternative but to purchase an older model of Tank so I can continue smoking as I did turn to Twisp to have a cleaner alternative for my Nicotine addiction: I cannot stay without smoking otherwise I would not even be buying these devices in the first place. So I wasted R 600 and had a total expense of R 1 400 to keep my smoking ritual going. It makes me feel like Twisp does not care about their customers and is just interested in exploiting the mechanisms of addiction to force their clients to continuously fork out funds to maintain the habit. As the Arcos is a brand new design it should of been considered that it may have flaws in the initial period of it being rolled-out and there should be more assistance given to their Clients other than a 'tough luck' attitude. I would really love to be refunded for the very expensive tank that worked only for 2 - 3 hours.
