Account hacked

My husbands Standard Bank savings account was hacked more than 2 weeks ago. It was reported and Standard confirmed that it was ******* transactions and they would investigate and report back within 6 working days to refund the money. It is now the 12th working day with no feedback. He has called twice and was told that it is under investigation.<br> In the interim (even though a new card with a new card number was issued by Standard Bank) another amount has been deducted.<br> Please respond as soon as possible.
