As far as i have seen this forum is dead. U don't get replies here
. Write your complaint to the support team.
They will act on it or atleast u will get a reply.
And to ur question about boosters, U will get free boosters from the game itself from time to time.
But dont expect too much, they will be very few.
Or u can use sponsor pay, but it is not available in most countries or u end up paying only.
And u win boosters by winning the championship which u can play at level 4 or by winning some special cups.
Hope i helped.
PS : I am also new to this game. Just been playing for 2 months
