i do e challenges and completed them but still no recived my car??? HELP!
What challenges are you referring to? Unicorns are only gifted by T10 for certain events, as prizes, or for posting in certain threads here on the forum. They are not normally available through regular game play. If you did complete a challenge that unicorns were offered up for, then be patient. It sometimes takes a while for T10 to gift them out to everyone who is eligible.
And given your other thread on this forum, if you were banned when the unicorn was due to be sent out you will not receive it.
