My money has been frozen for no reason. I can't buy food!

I Recently opened a bank account with Discovery bank.. after doing the FIRST deposit into the account they have frozen my account for a whole week and I cannot access any of my finds or do any eft out if the account. This is absolutely ridiculous I have been calling every day.. I have no money to buy food!!! How can you just freeze my account and not tell me.

I cannot believe that this bank can be so unprofessional!
