Nedbank lack of response to client complaint.

I needed to obtain bank statements and was unable to process them on my Nedbank Money App. I contacted Nedbank *** for assistance. The call center agent did not offer to guide me on how to download the bank statements and neither was I told that the bank statement would be R35 per statement, I proceeded to request the bank statements and they were emailed to me. If I knew this I would never have continued. The next day my bank account was debited with R840. I logged a complaint with Nedbank Ref ***3 on Friday 1 July 2022 the agent indicated that Nedbank would be in contact with me within 24 working hours. I tried again today 6 July to contact Nedbank as they have made no contact with me. Hence to say that the 1st person that answered the call took the complaint number from me and then redirected me to the complaints department, the number just rang and then eventually cut off. This has resulted in insufficient funds in my account and has resulted in debit order being dishonored.
