Can I get a refund on a unauthorized purchase?

$38 charge from iTunes showed up on my bank statement & I do not recall authorizing that charge. I’m assuming it should have been for a photo editor but I wanted to only purchase the 1 month plan for $5.99 I believe it was. I have not seen that reflect off my bank statement, as I’m now assuming somehow a glitch or something must’ve happened or something went wrong between then because I would not have paid $38 on an app like that
