TERRIBLE SERVICE FROM STANDARD BANK, MY BIGGEST MISTAKE

So, I have been having the standard bank Mymo account for +/- 4 months now. Each time I try to make an online purchase I don't receive an OTP number. I have escalated this matter so many times to standard bank and each time I get an excuse about their systems being offline or having technical issues. I seem to have made a mistake by moving from FNB to this confused bank. They cant sort out something so simple and everyone seems to be confused! I finally spoke to someone that Karabo claimed to be her senior and her name is Elizabeth Lethoba. She promised to come back to me and I hope she will do the right thing.
