Poor service from African bank

I paid R19000 from my african bank my world account into my FNB eazy account on the 30th of December 2023. Today it's the 17th of January 2024 and still today the money that I paid into my fnb account from african bank is not reflecting in my fnb account. I have called african bank several times for assistance and I have been told that my query will attended to but so far nothing has happened. The money was meant for my children school fees and stationery. I am so disappointed and frustrated that I don't receive any help from african bank
