Have just had £100 taken from my Paypal via 'paypal mobile' to an email address I've never heard of. Nor do I have any idea how to use Paypal mobile. I think I've managed to reverse the transaction, but I'm pissed off & worried (which I could really do without right now).
Anyone else had this? What do I need to do to secure my account and prevent it from happening again? I'm presuming someone had my password,although I have no idea how they could?
