Hello Dom,
I am sorry to hear that you had this bad experience.
Here are some suggestions:
1. Please dry clean the 510 connector on your unit to ensure no foreign materials/e-liquid inside it.
2. Please check if contact pin inside the 510 connector is exposed and centered.
3. Please use a flat stick or something similar to push the pin up and down repeatedly to ease a stucking issue. Would you please try a new spare coil?
If you have any further concerns, please feel free to email our official customer service:

Happy Holiday! Keep warm and Take care!
Best Regards,
Innokin Team
