HOUSE OF TOBACCO KOLONADE - IQOS SMOKING UNIT

I bought an IQOS smoking unit from House of Tobacco on the 22 June 2018

When i finished charging it i took 2/3 puffs and then the unit turned orange the call centre from IQOS phoned me to check if i am satisfied i told the person what the unit does he explained to me to reset the unit witch i did. Still no joy i had 2 of these sigarettes and it did not last 4-6 minutes as said in the pamphlet. I went to House of Tobacco Kolonade where i bought it and there is a sales person who opened it and tested it, He took a few puffs and said the unit is working, The unit was not on for even 4-6 minutes, he phoned the owner of the business and she said i must sort this out myself with IQOS as they don't uplift the damaged/broken IQOS units from her. My point is i bought this unit for a reason paid alot of money it is not working correctly i don't wnat this product anymore.......... the consumer law states that i am not happy with and product i can return it within 14 days of purchase. the owner does not want to speak to me she does not answer her phone and she is not everyday at the shop. i emailed my complaint to IQOS on there website on Sunday the 1st July 2018 and up to now no reply at all, i also tried phoning them but no answer. i feel that the store that sells this product must take back the product as they are selling the product and i bought it from them and they took my money!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
