Swindled by Bank

I feel have been swindled by Zanaco L/stone Branch. On 6/02/2014, I
deposited K1200.00 in my a/c using my old a/c no. On 10/02/2014, I
discovered my a/c wasn’t credited. I reported the matter and was told
the teller who did the transaction was working from a different branch
and they will contact him. The following day, one was told money was
deposited in some one’s a/c who withdrew it almost immediate. On 7th
day was told they tracked the person and now have to wait until he
pays back the money to the bank on 27/02/2014. Please help me have my
money back because the bank already agreed it wasn’t my fault. Thank
you
