Win 2 mango tickets dcsm

MANGO AIRLINR FREE TICKET COMPETITION. I enter the mango win 2 tickets competition. I follow the steps. I share with 20 friends and when I want to claim it didn't give me the claim option again just said i must follow the steps, then i did it exactly as the said the first time and still not give me the option to claim. So I actually sent it 2 times,because I want to get back to the claim part, 40 friends that I have share it with. So is this a **** just to get your info to our friends when you share the "compitition link" and advertise mango flights? Thats not fair to me!! We try to win the tickets and then after sharing 2 times still you never win anything!!!!!! Because going back to the page it said you must share I am very dissapointed. I am going to warn everyone thats a ****! Getting our hopes high for nothing. J. Lloyd
