Bad quality product and pathetic customer service

I started smoking the original twisp and I was more than happy to pay for the expensive liquids as the product was great. I then got the twisp aero and they must of changed the supplier of the coils as one barely last two days before you can taste the burn and your entire expensive flavour cannot be tasted properly. I was told that the coils last weeks .spending 150 rand on coils a week is beyond ridiculous. I spent a lot on the device already. They quality is pathetic. Upon. Further research I found out that there are lots of people who feel the same way. What are you going to do about this as I was promised a quality device with coils that didn't have to be changed all the time. I got hold of you guys through Twitter and for a week now I have been promised that someone will call me. Each day I'm told sorry today someone will call. Today finally someone called and when I answered they said nothing , I introduced myself again and they hung up the phone is this what the company is like? Bad service and bad quality? What are you going to do to correct this problem. I am beyond annoyed.... If I am not contacted I will take to social media to let everyone know exactly what they in for
