Standard Bank bad serive abroad.

I am in China and have sent them emails asking to help me log in because I can't as I don't have a South Arican cell phone number and have been out of S.A. for over a year. After multiple emails asking the to advise on how or help me to log in I still have not been helped with this. This is terrible service and I feel like moving to a different bank who helps their customers (The rest of my family has left them already) when I get home after the pandemic ends. They do know about it as I asked them to unblock one of my cards in these emails but they refuse to help me log in. I can't mannage my funds but they send me an email telling me to use money in a loan account.
