No reply from Standard Bank in SEVEN DAYS!!! Disgusting Service.

I'm utterly disgusted with the service that Standard Bank are giving these days. On 07-01-2019 I logged into my Standard Bank Mobile Banking App to send an instant money voucher to someone who was in urgent need of money but the Standard Bank Mobile Banking App kept on kicking me out after filling in the amount / choose a pin / my reference and then when I say confirm it didn't send me an OTP and kicked me out and took me back to the login page. It also logged me out after about 20 seconds and said it logged me off after 5 minutes of inactivity even though I'm only logged in for about 20 seconds. After numerious failed attempts I tried Internet Banking on my PC Browser. I send an instant money voucher and after about 5 hours the recipient did not received the voucher number. I again logged into Internet Banking and cancelled the voucher of which I then got refunded for. So after all my failed attempts I emailed both ********** and ********** to tell them about the problem and guess what? Until today nobody, I repeat nobody from Standard Bank has in more than SEVEN DAYS rep**** to me yet (yes I did check my Spam Box). Standard Bank you are starting to show your real colors? Up your game Standard Bank and take more care about your customers!!!
