It seems that many people bought tickets for a Red Cross draw, in combination with the Once lottery, with the prize of a Mercedes car. The draw was on 28 February, and it transpires that there is no easy way to check which number won. On the ticket, however, it says that one must call the Red Cross itself, something that has frustrated many participants, it appears, either through receiving an engaged tone, or simply not being able to communicate in Spanish. I’ve rung this morning to find out the winning number, which is 94106. I hope this helps.
