PayPal also has a nasty habit of randomly holding the money until the receiver confirms everything is okay with the item. You can have a 100% clean account with no prior claims, but they still do this. Particularly on high value transactions. Too many people did the whole "low balance" thing.
And as the OP has experienced, they randomly take money out of your account without consent.
To the OP: Call your bank's fraud department. That is what PayPal did there. They cannot just take 26 times the money you gave them permission to do just because they felt like it. This wasn't with PayPal, but I had a company do that with me (cash and in person is my current life rule now). Wells Fargo reversed the charge and gave me new numbers so the company in question couldn't do it again.
Edit: Is there a way for you to blacklist the phone now? Since they made the claim, make it so.
Yea I called AT&T explained the situation and they blacklisted it. Told me I could unblacklist it if I got it back no problem.
As for the bank thing, at this point I want eBay and PayPal to be the ones out money I have the utmost confidence in my ability to argue my case in court. But do I want to miss classes that are essential to my career? Screw it I want to make an example, I warned eBay and PayPal numerous times this was fraud. If they want to be the ultimate deciders and not take the time to actually review the evidence (the buyer presented no proof of a blacklisting or used phone) then they deserve to eat the cost.
Besides the fact my bank said I could file a ACH claim with them but it was unlikely to be reversed. Throw in all the addicts and fake scripts at my pharmacy and I just want the universe to stop throwing my curve balls!
