Received a call from three saying that the phone had been blacklisted (guess i should never have bought off ebay

), and they said to fax (yes fax, who still uses them?!?) them the details of the transaction to prove i bought, and so did not steal it
Seems a bit weird though, because i received the phone in the box, unless somebody made a note of their imei number before the phone and their box was stolen, and then reported it 2 months later
I had a hunch that maybe three is doing this because i am not using the phone they gave me with the contract, or am i just being paranoid.
edit: FURTHERMORE,
i just used the checkmend imei checker (cost £3), and it said:
"We have no records to indicate that an item with indentifier ****** has been reported lost or stolen"
So what do you think stolen or not stolen?
