Balance and card charged instead of just card

[differentiate]

I'm not 100% sure where to post this, but last week I bought a car part for a relative and paid using his bank card through PayPal. I checked my balance today and realised that it had charged my PayPal balance along with his card. How would I go about retreiving the money from his bank?

Thanks.

Ask him for it?

Is that what St Piran would recommend?

Nope, just common sense.
