Poor service

I payed 2500 today from the wrong account number and went to the bank to be assisted with the reversal and the bank doesn't wana assist me they saying the have to ask the person of the wrong account number first to reverse the money which fail to understand as initially the person did have the money in the account nd the bank could see on my app that I'm the one who sent the money.in future I won't recommend anyone to use capitec bank as the don't take care of the clients..I was treated like a fool in the branch,maybe that's WHT they teach them
