Support does not even bother to reply

I bought a twisp from Takealot, excited because I would finally be able to stop smoking cigarettes. The product was faulty to the point where the mouth piece leaked and it became extremely hot, I just took it for granted that this is the way the product worked, until it stopped working after only having the product for a few days. I tried everything but it would just not charge, I left it on charge for days but nothing. I finally decided to send an email to twisp support, stating I would rather resolve this with them, than write a report on hello peter, but they flat out ignored me. I sent the email on Sunday 13th Feb 2016 and got a reply they would contact me within 24 hours, I have still not received a reply. This is frustrating and I have started smoking again. I think this is unacceptable service, quick to take your money, but after sales service is non existent.
