Standard bank doesn't have controls in place over Cheque accounts

Standard bank doesn't have controls in place over Cheque accounts,

I have lost my card which had in the account R0.00 balance and not in use , later on I was told account is owes R3000.00, which I then reported the *****/theft case on the card at the standard bank branch in Centurion lifestyle (case no. ********** ),and emailed through the bank statements as I was requested to send through

Automatic response after sending the statements: " Dear Sender We acknowledge receipt of your e-mail and will provide feedback within 1 business day of receipt."

about 7 months later(now in August) I get a call from Nimble collections, ********** 750/ ********** 028, saying that I need to urgently pay R9000 that I owe to standard bank cheque account

a week later I got a call from the same Nimble collections, ********** 750/ ********** 028, saying that I need to urgently pay R11000 that I owe to standard bank cheque account
