Quickly...should I accept this return for a phone I sold that was later blacklisted by the Carrier ...either morally or legally? I can't resolve this issue in my head and am looking for advice.. Scenerio - I purchased a used smartphone on eBay (who had purchased it from non-claimed property sale), activated and used it for a few days, I then resold it on another forum and that buyer activated it on a different carrier and has used it for a few weeks. Now the buyer says their Carrier blacklisted the phone, after it was activated, and wants a refund. I verified it was blacklisted, after activation, but find it suspicious. Apparently the "original" owner is doing an insurance scam OR didn't fully pay for the phone before they lost it through the property sale. I already told the buyer I do not feel obligated to accept return since the phone was activated when I used it and they have used it already...even though a short time. Any thoughts on my obligation to accept return or how to handle? Thanks. I am expecting paypal to send me a notice but I will probably resist that (I don't like feeling like a crook even though I didn't do anything wrong) Thanks all!
