Using wrong acc number

On the 01 October 2018 my dad transferred money for me to my Capitec acc using account no ********** 488, in the branch however when my dad deposited inside they used my other acc ********** 329 and then my dad called to ask if I got the money and I asked him to check the account, when he went back to the branch to ask why didn't they put it in the right account which was written on paper ********** 488 they said there is nothing they can do I must just transfer it back to the account I want it in, he spoke to a teller named Michelle, I then called and spoke to the Manager Chad Jacobs who said there is nothing they can do I must transfer it myself, as all accounts are linked to me, but then I specified the account number then he said to me I can call Head Office if I want but they cant do it, the same thing happened in April same story in Rusternburg, why cant they check and verify the acc number written, how much more can I specify??? this is so inconveniencing for me.
