Hello, I’m new to using any kind of rebuildable. I recently bought an ijoy limitless rdta/rda combo. When I took the rda base out of the package the center post (contact post?) fell on the floor and has disappeared. Does anyone know where you can get replacements? I have googled several different things and all I keep seeing are the screws that hold the coil in place. Surely I’m not the first person to lose one of these. Any help is appreciated, thank you.
