Bad services from ABSA bank

On the last day of October there had been money paid out of my account which I have not authorized or did not perform, I then opened a ***** case with absa bank to assist me from the 30th october and I still haven't been helped as yet and it is the 23rd of December I haven't even paid Bill's from the previous month this totally bad service from the bank, I had received emails saying someone will call me and no one called yet. They have shown no care or interest towards the situation.
