Money missing from account - Bad Service

Hello Peter Please help out. I have been a very loyal client to Capitec Bank for many years. I am not happy with the way they handled my dispute. I lost my card a weeks ago and called the call center to have the card blocked. A few hours later I noticed that I also cannot access my cellphone banking. I then called again that's when they told me to go to the branch to check what happened and get new card. To my surprise when I got to the branch they told my there's no funds in my account ( Here's the problem...Nobody withdrew any money from my account. There's also no activity of funds been withdrawn from my account). I have been to the branch 3 times already, they keep sending me back with no accurate answers as to how the problem is going to be solved. I am a family man and this has caused great distress within my family. And my salary is paid into that account. What steps should I take now, who am I supposed to call? Kindly help
