Disgruntled client

I sent the wrong person money late last night using cellphone banking unfortunately I realized my mistake this morning. When I called Capitec bank to rectify the mistake, they tell me they'll need permission from this person to take the money out of his account. The icing on the cake is that upon further investigation the person has already spent the money and there is nothing the stupid bank can do to get my money back. The only good thing that came out of this event is that I realized that I'm not a valued client to capitec as I thought I was compared to the guy that took money that didn't belong to him.
