FIrst take a deep breath. Most of us have been where you are right now. Gear broken Jonesing bad and nothing to vape.
If as you say you cannot return it to the guy on eBay then you have nothing to lose by trying to pull the pin on the connector slightly. It might work.
If that does not work I would be inclined to believe you have been sold a bad unit to begin with. THe problem is on eBay eCigs are banned. Both you and the seller will lose you eBay accounts and your Paypal accounts if you report the seller. There are jerks on eBay who will happily sell you their dead gear knowing you can't touch them and if you do accounts are closed and they screwed you twice. It is why I refuse to do eCig business on eBay.
If you need to smoke until you get setup to vape so be it. Don't beat yourself up for it. Count the ones you don't smoke rather than the ones you do.
EDIT: because I managed in my insomnia ridden brain to combine 2 different answers to 2 different threads into one post.
