Hello! Please, can you help me? I have a big problem

Hello.

My sister's kid installed these apps without my knowledge, and he told me he didn't know anything about the premium subscribe. In fact, I think he tried to cancel it, but didn't figure out how.

It was a mistake, I didn't give permission for this purchase and only found out about it last night! The transaction went through yesterday, it has been a day since my bank card was charged. I will not use these programs, this is not some kind of trick. I don't need them.

Please help me get my money back and cancel the subscriptions. The exchange rate of dollar to tenge is very high now, and I can rent an apartment for half a month on this amount. This was my last money. I have to pay the rent for the apartment, but I have no money! Please give it back to me, I'm begging you
