Standard bank

I visited the Standard Bank Westville branch in Feb 2022 to change any notifications from sms to email. All the necessary paperwork and signing was completed. I have the app on my cell phone which works great but I cannot login to internet banking on my laptop as it still sends a OTP to my cell phone number which was cancelled in Feb2022. Since then (6 months) I have phoned and emailed to try and correct this. I am trying to do this from Europe and have emailed every department I can find to no avail. I sent someone who I gave the necessary power to handle my accounts into the bank to try sort this out. Initially we went in together to ensure that they had everything they needed. This person cannot do it either My debit card has expired and I cannot order a new one as the bank does not recognise the card number which they actually show on the cell banking app I cannot manage my account info as necessary on my cell and need the internet on my laptop to stop Vodacom from ******** debits.
