Steam problem

Hey
i hope someone can help me
i have a problem
i wanted to buy black ops via steam with a paysafecard
but when i pressed buy it was loading all the time
then i decided to end steam and try it again
now and my games there is black ops but when i try to start it says
that the transmission is not completed yet
i coulnd even write the code of the paysafecard
this means that i didnt pay
but now i cant play the game
and cant buy it again because it says there is a problem

hmm maybe give it a day to calm down, to see if you did/'nt recieve the game,
maybe restart pc, and try again.

thx for answering
but i restarted my pc again and nothing happened
you really think i should wait a day
could i make another steam account buy it there as a gift and send it to my main acc?
