I have no idea what to make of this situation. I don't think it's a scam. That is, I am pretty sure it really was FxTec (Francisco, bot or not) asking for my money and I'm pretty sure the Paypal invoice was really from them, and assume the same with yours. So, to my mind, that makes the most likely scenario that they somehow gave you the wrong tracking number (more likely, I think, than they sent your package to someone in GB, though we can't rule that out). Nowhere does FedEx indicate that you ever figured into this shipment. It may even be that your battery hasn't actually been shipped at
