Dissarisfied customer. Faulty product

Skeptical when purchasing the device an electric cigarette Atlantic nautilus ...and stating if I'm In not happy I will bring it back for a refund which was agreed. I was also told it is under 1 year warranty, I purchased the device, one day later I was back in the shop complaining about the terrible flavor and coughing from the device irritating my throat, I was told by the sales man and woman that I should persist for 3 months, I did and went back complaining about the same thing, also the flavour was leaking into my mouth, when the sales man tried the device the same thing happened to him, they advised me it could be the coil or to Change the flavor ... They charged it in store and it seemed fine, I used another flavor, 1 more time, I persisted and finally unhappy and dissatisfied I returned it for a refund rejecting the product. I was told to bring proof of payment which I then presented, I was phoned by sales person after sales person to area manager, to supplier, to owner all claiming there's nothing they can do...

I paid R310 for a product that never worked I was also then told it only has a 6 month warranty when it was sold to me and stated that it's a year warranty... I returned the product 3 times and they said they can do nothing....in the shop the sales lady also informed me the device is faulty and many have been returned. Extremely unhappy dissatisfied, I will never support JJ CALE GREENSTONE. If it was possible to give I zero rating I'd do that. They don't deserve 1 star
