No response

Good morning<br> <br> On the 11 June 2015 I went to my local outlet. I bought the new smaller twisp, but the one battery didnt work. Also I was not happy with the twisp. The flavours and usage was poor. I wanted to know if iIcan exchange it for the first model. The sales person told me that they have a lot of complaints about this, but he cant exchange it, I must email the manager Robert Horn. I sent him an email. On the 15th I still had no reply, and asked Robert if he received my 1st email. He rep**** that he is waiting for feedback from his office. On the 25th I emailed again no response at all. On the 1st July I forwarded the mails to the support@twisp adress, got an automated response saying someone will contact me. No one has. I dont want a refund just an exchange. The service received from Twisp is pathetic. The customer care dreadful. The sales consultant cant help, the manager doesnt respond. Is it because twisp is the only leading brand that they have this attitude? I just want an exchange.
