I am a newbie at vaping and already have problems, I only used my joyetech eVIC VTC for one day and had problems with it not vaping anymore and leaking around the top of the device, I am asking if anyone knows what is wrong, I would love to start using it again but I have no idea what would be wrong, I have tried to get help from Joyetech but everytime I send them photos they ask for more photos, I am frustrated, this cost me $80 and I need help to fix my problem, I am 53 and want to use this as a replacement for cigarettes, please help
