Duplicate Debit Order

I am in China and logged into my account. I was shocked to see my account had a negative balance. I then saw a debit order had been duplicated. In addition, I was charged a R100 honouring fee. I am guessing that is because there were not enough funds to pay the incorrect duplication. I am not going to waste my time contacting my personal banker via the app. The last time I did that, I had to sort out the matter myself. I have said several times before, find me a personal banker that was good like Innocentia. Why am I paying extra for non-existent service. In case someone at the bank does not think - it has happened before - I am in a different time zone from South Africa. I am currently six hours ahead South Africa, so please do not try to phone me at 17h00 South African time. Also, do not pretend you really tried to get hold of me and then close the case, as often happens. I have two e-mail addresses, WhatsApp, SMSes and a phone number. It is definitely possible to communicate with me.
