Absa accounts getting hacked

I have received the worst service from Absa within the past two months. I have been getting messages confirming my login in into my account when it was actually not me. I went to the bank to reset my passwords and pins. Today it happened again and the ********* managed to do two cash sends to an unknown number .I immediately called absa ***** dept to cancel or block my account. They gave me a ref number to take to the police without advising that I needed to take a stamped bank statement to open a case. I was told it will take 15 to 30 days to do investigations. This is not the first time my account was hacked and its surprising it's becoming a monthly thing.
