Pathetic bad service

On the 18th of June I was a victim of Cyber Crime where my account was used for online shopping without my permission and knowledge. I received sms notifying me of four transactions within few minutes. I immediately block the card and within 15 minutes I was at a branch where I reported. I was told that they will investigate and come back to me within 15 days. I have done many follow ups and I am always told that they are still investigating. No one is coming back to me, I am the one who is always doing followups.
