Switching to another vape brand

I've given up on Twisp's products and service. I just reported a coil that worked for about a day and Twisp Kolonnade refused to exchange it for a new coil. The Tyko is a pathetic product that burns out coils quickly, even when used sparingly. If this service continues I'm switching to another vaping product. The two women who work at Twisp Kolonnade are kind and helpful, whereas the man who works there often seems to be drugged out while working and refuses to do anything when it comes to faulty coils, even if you had your slip to prove your purchase.
