Unauthorized transactions

We notice unauthorized transactions on our account and reported it to the bank. They block the relevant card and more transactions was done after the card was blocked. We reported it as well to the bank. There response was they will investigate and report back in 6 to 8 weeks. We received notification that the new card can be collected at the bank. An transaction was done before we collected the card and as per the bank the card status was blocked. We did not collect the card and the bank told us they will investigate and report back in 6 to 8 weeks. I was also informed to disable the online shopping. The will replace the card free of charge. Now I'm very concerned about the rest of my money in the account.
