I do appreciate the help and everything here, I hope that's not misunderstood.
I knew I should have rebuilt the coil from the get, but I thought it was fine because that's the way it came. This rda was still shrink wrapped, so however it was built, that's how the manufacturer built it. The coil was the strangest I've seen personally. It was probably 24-26g wire, somewhere around 6 wraps, and the strange part, it was a dual coil build, on one wire. By this I mean, one end clamped in one negative post, passed through the positive post, the other end clamped into the other negative post. Never scene a build quite like it, and I've watched eye tiring amounts of build videos on YouTube.
IF the rda was sealed by the manufacturer with the coil built into it, then the liability is on the manufacturer, not the B&M. But being that it is more than likely a clone, dealing with the manufacturer may not be an option. Each B&M have their own policies on how they would deal with these types of situations. I always feel blessed that I live in an area where competition that there are loads of knowledge and decent quality service.
I feel for you man, and just chalk this up to a lesson learned. I would never fire up coil on an RDA that I did not build myself, seen built, or witness it fire up to verify that it works.
I think the coil you are talking about is the Sleeper Coil
