Lost hope... this is a scam. LOST 150 USD TO THEM.
Waited for nearly 3 months. Tried two different iphones (Xr ans Xs). NO RESULTS. For each phone they told me it could not be unlocked and I could not get a refund, although I verified the phones before submitting on their suggeted websites (swappa). Now they do not reply to refund requests. AVOID UNLESS YOU GOT MONEY TO SPARE!
Exchanged some messages with "Luke", who stopped replying as soon as things went south. Worst service I've ever experienced.
