Payment missing between my accounts

Yesterday i transferred R1000 from my Savings pocket to my cheque account. That money was deducted from my savings pocket but never made it to my cheque account. I thought I Should wait it out and it will eventually reflect but that never happened. How can a payment made between my own account disappear just like that?<br> I just feel i cannot trust this bank anymore if such ***** things are happening. Usually if i make a payment to my cheque account from my savings, that payment goes through Immediately as i am tranferring between my own accounts, but this one has just vanished. This is so frustrating.
