Worst experience ever with standard bank

Worst experience ever with standard bank, sent an ewallet voucher to myself because I didn't have the card with me. Collected the cash from an ATM and when I got home to count it was R500 short. Logged a call with standard bank, they came back and said their technical report shows that l collected all my money and the lady I spoke to said I should have counted the money immediately at the ATM and also waited longer to see if all the notes were out. I am so ****ed off, having been using standard bank for all these years and 1st time i have an issue they do not want to refund my money yet its their machine that took my mine. Nonsense!!!!
