E-Xhale K10 Vape Smokes itself

On the 17th of September for the very 1st time ever I bought myself the K10 Mango Bomb after being introduced to it by a friend. For years myself and my husband were and still use Vuse epod systems. But I so loved the great taste of the E-xhale Mango Bomb I wanted to spoil myself. Unfortunately the only place I could find one was at Engen in George and we live in Mosselbay. So I thought let me get it and have it when the time is right I can start using it. Obviously I still had a few Vuse pods that needed to be smoked. So only every other day I will take a puff or two from the Mango Bomb unit. On the 24th of Sept it started smoking itself and actually heated up to such an extent that we feared it was going to explode in our house and placed it outside to ensure our safety. I did reach out to E-xhale and their feedback was because it's not within their terms & conditions and return policy they are not able to refund or exchange the unit. I do feel that's a bit unfair but my main concern is the safety of others and their loss when their units start boiling and smoking them self's.
