Good Product gone bad

<p> I bought 2 Twisp Aero's in December 2015. Loved the product until the coils s****ed to last no more that 6 days. It used to last at least 2-3 weeks. I wrote a letter to Twisp to which they told me to leave the faulty coil at the nearest kiosk which i did. No feedback. Anyway, it is not so much a matter of the coil being faulty but rather the quality that became poor after Twisp became so popular. I now have to buy a new coil every week and the prices for the upkeep became so much that i might as well go back to smoking. Honestly loved the product but if quality goes down because of popularity, what is the use of boasting with a smoking alternative. My fiance also send a complaint to Twisp and they simply deleted his mail without reading it first (as specified on read receipt). Not nice. So many people are complaining about the same problem but nothing gets done. Please help. Why ***** up a good product.</p>
