Private banking customer ditching Standard Bank

I have always been a good customer of Standard Bank in the past 20 years however I feel that their service compares to what I expected from a government institution like the Post Office. However they just kept on treating me like dirt. Declining Insurance claims without solid grounds, not responding to claims logged, etc. They claimed I did not maintain my thatch roof even though I have evidence (and photos) of this. Then a swimming pool pump - they called it wear and tare - really?

The poor private banker was trying her best but the rest of standard bank cannot deliver.

The latest nonsense was I have closed my account with Diners in December 2023 and in December and January they have instructed a debit order of the minimal account of R50, mails, etc.

How are they surviving as a bank?
