Online Banking App bugs made my fault

I used the mobile banking app to pay beneficiary. I entered acc number wrong the first time (my mistake) and paid the amount to the wrong account. I accept responsibility and asked for funds to be recalled (and incurred recall fee). Edited beneficiary's details. Got one time password on phone. Entered OTP in banking app. Got sent confirmation that acc number had been changed. Paid amount again. On confirmation see that account number hasn't been changed! BUGGY APP. tried again. couldn't change details. Call center told me it's my fault. Told me I can't get my money back and need to go through recall process and pay R250 odd rand to do it. <br> <br> Standard Bank app basically just stole my money by having bugs. Standard bank won't take responsibility for their bugs. Don't use their Online Banking App. If there is a bug and something goes wrong, YOU ARE RESPONSIBLE IT IS \SELF SERVICE\". Can you believe it? How are we supposed to use self-service if it's broken? <br> <br> Losing trust in my bank"
