Subiectul: Warning before spending CREDITS

I just saw I was charged 123 credits for "advertising" the sale of a handball player.
I never advertise any player. Either it is an error or they counted an accidental click.

They should put a warning, "Are you sure ..etc?" as is done nearly everywhere. It's unfair to just bleed us dry.

good evening,

how could I buy credits for another user?
