I don't know what to do

Hey guys, I already pretty long time thought about boughting skin on Gnar, Dino Gnar skin. But, I'm not an adult, so I don't have credit card, and from our country it's pretty expensive by mobile. I really dunno what to do, I'm just a girl who playes Games a lot, but I never thought that I might get catched to something like this. I guess there is no option to get it, but I'm asking you guys if is there anyone smart who knows other option, or someone kind and nice who would bought me a skin. I think no one would do that, but I still can ask, can't I? So, that's it, I hope it didn't bother you much, Thanks, and have a nice day :)
