World of Warcraft Help?

I’ve bought my mums boyfriend the World of Warcraft game for the computer. The shop assistant didn’t tell me that i get a free ten day trial then i have to pay �8.99 subscription fee. Is there anyway i can bypass this because i find it silly that I give him a present that he has to pay �8.99 a month for any help?
Answer #1
I think private servers is the only way. If there is, I don’t know.
Answer #2
And what exactly are the private servers? i have no idea about the game or anything so im pretty stupid lol
Answer #3
The Private servers are servers that don’t require you to register or even own a legal copy of the game. All the downloaders of the game use them so you can find pretty nice private servers. Good luck mate ^_^
