Some people have vapesourcing success, others not so much. I think they must have a fair amount of volume.
But if you are having trouble, do visit their forum and post directly. A member of the staff will be there to help you (if not on the weekend, definitely by Monday). They're probably going to ask for your order number, so you might want to post it upfront (if you are comfortable with that, and no one but a staff member at Vapesourcing is going to recognize it besides you, in any case).
Best of luck,
Anna
