JazzCash Fraud ?! – Amount Gone Without Consent! Need Advice

السلام عليكم

So basically I set up a JC NextGen account for my brother some months ago, but now that he's 18, we’re switching it to a normal one (if that's possible).

Last week, I sent him 25K PKR, but a day later, 23K was transferred to an unknown recipient—without his knowledge!

There’s no trace of the recipient since the transfer was via Raast, and oddly, they withdrew exact amounts (10K & 13K), as if they knew his balance.

When inquired, JazzCash helpline initially claimed they had no details but later said they filed a complaint with the FIA—yet refused to provide documentation!?

I've heard of similar cases with SadaPay, Meezan, etc., and always thought that people would have mistakenly confirmed the transactions and won't remember. But now that it happened to my brother, I need answers. Mind that he's not an illiterate when it comes these tech/finance things.

How can we recover the money or hold the perpetrators accountable? Any advice would be appreciated!
