No customer service but high monthly fees

I had an account with standard bank for almost 30 years and closed it due to their lack of customer service and high bank fees, even baught a new car once I changed banks. While I was still a client with them, I had opened a savings account for my daughter when she was still a minor, so obviously once she started working, I even went with her to change her savings account as a minor to a cheque account because she had a full time job and started earning a good salary, they even wanted to give her a credit card with a limit of R60 000, pre-approved because of her salary. Her whole dilemma started when she got a new phone and cell number. She went into standard bank, saying that her details has changed, she has a new device and new number and cannot even access her banking app, it still sends an otp to her old number. She has been to the Grove branch multiple times, made calls and this has still not been rectified, their monthly service fees are rediculous and there is absolutely no client service. I have told her to close her account because this is exactly why I closed my account. It's like they don't even care. Leratho at the Grove branch just said, there is nothing she can do when my daughter said she is going to close her account and go to another bank where she actually gets service. It seems like Standard bank just wants their fees, well they take it every month, but where is the customer service and how do you resolve this, they don't even have a customer care number and e-mails are just acknowledged by an automated system and never rep**** to. Please help in resolving this and taking action against this blase attitude, hope there are more people that will stand together against this outrageous abuse and miss use of their customers.
