Extremely unhappy client

My name is Zandile Ndwandwe, I’m very frustrated by ABSA bank, I was financed by it and I had an early settlement. Only to find that they need to refund me 7024,it’s 2 weeks now when I call they keep changing stories I even told them I need that money for registration even today I called they told me my money was moved to non existing accounts because they wanted to close vehicle account, my question is why did they decide to move my money and close the account without contacting me.. I need this money by close of business day tomorrow
