Blocked account

My bank account has been blocked. No one said anything. Went to swipe and my card said decline. On Thursday i call standard bank and was told that my account has been blocked. And ***** section will call me. To date no one has called me and no one is saying anything about why my account is blocked. I believe i have a right to be told before hand why my account is blocked. My debits today they are bouncing back and i am encurring changes that i do not know why. I cannot buy food for my kids because my account is blocked and no one is saying anything. This is very frustrating. Standard bank has lost its value. I might as well move my bond and my salary to another bank that put its costumers first. This is *******. On top of that i am using my own airtime and no one is assisting me.
