Standard Bank Private Banking not worth it

Standard Bank Private Banking is a total waste of money and simply not worth it. The so-called private bankers never answer their phones or emails. If they call back it will be after hours. I called to report a potential ***** on my account. My private banker promised to call back in 10 minutes; he called 2 hours later and asked that I send him an email with supporting documents. I did that yesterday afternoon and up to now, there has not been any feedback. I sent a WhatsApp message and made three calls all to no avail. Will definitely be leaving !!
