Strange - I also got the same email asking for telephone confirmation after the paypal payment was authorised. I sent them an email asking them to cancel the order.......and within another 5 minutes someone had tried to access my steam account (lucky I have 2 factor authorisation activated). Be careful with this one guys!!
Well seems they changed the mind about the authorisation wierd
Oh i didn't have that issue, this company has been posted many times previously so i cant imagine them being dodgy, however saying that, it does seem odd.
Tried ordering this and paid through paypal,got an email saying they needed to verify me and needed my phone number to give me a call. Now I would understand if this was from paypal, but it was not it was from mmoga who didn't handle the payment? it seems dodgy to me. I have asked them to cancel the order and refund.
