Faulty products being sold!

I am very disappointed in Twisp products. I started twisping years ago as an alternative to smoking. I am currently smoking the cue device previously had a long, time consuming and inconvenient back n forth battle with their pods having manufacturing faults before they finally dealt with the problem. On the 6/11/19 -less than 5 days ago I purchased the TYKO vape as a gift for my partner at the century city branch only to be extremely dissatisfied. The store assistant set the vape up for me and I he puffed on the vape a few times within the space of an hour and the coil completely burnt out giving an awful taste. We had to go back to the store again and were told this is a common problem with coils that are included in this device package. If the company knows the coils are faulty I do not understand why they are they still selling them????They then replaced the coil with another gold coil. The gold coil lasted literally 2 hours before it started puffing weird. It sounds blocked and bubbly, makes a firing sound, has a horrible and unpleasant feel. To add to the devices issues the paint/cover on the device is already s****ing off – this is after 1 day!!!I have a picture I took to prove it. I would like a full refund for this product including the liquid
