Bad Service

I had a terrible service at absa smith street durban branch. The bank teller are *********** ,I went there to transfer funds from my savings account to my personal account,I advised the Teller that I have a outstanding balance on my personal loan,will the debit go through if he transfer the funds on my personal loan,the Teller said it wont.He then transfered the funds.Immediatelt the debit for my personal loan went off. I went to the bank I told him what happened,he told me to call personal loan dept. I did and I was given a number to call ,the number I was given doesnt work,it always busy. Please rectify this as the teller mislead me.
