I ordered 2 new batteries last week to replace 2 that had bad threads, I was told I would have to send the the old ones back, but I didn't receive any return postage, well since I recieved the new batteries I have gotton the old ones to work, now I have 4, 2 I paid for and 2 for free. I am trying to keep a good relationship with vapor4life,you guys have been good to me since I started using your product. Will you send return postage, so I can send them back?
