Taking money without my knowledge

Hey my niece was downloading games on my phone , she didn’t know any better and downloaded a arcade game I guess , as soon as I seen it I deleted it thinking it was gonna delete the subscription too , but it took 4.99 and I really need it my birthday is Friday and I need it before Friday y’all are saying y’all will look at it Friday y’all are not that busy so if you can pull some strings and please help me get this money back it would be very appreciated I’m actually going out of town Friday so I need it to finish paying for a very important ticket before friday so I can actually leave friday
