Got personal email invitation to register IB Plus and participate in that promo. Made a reservation, booked 10 flights(about 275€ total). Only 2 of them the FF number was saved, others I added manually later. Got email that send a identity proof. Since I did not remembered which ID number I added to my account, I sent ID card. Then ping-pong started. After 4 emails of denial to activate account, I sent two copies of my ID and passport in the same picture and asked which one is fake. After that the account was activated and 90k points were added on the same day. I have redeemed 85k miles as for today.
