Money disappearing from my housing loan account without any transactions showing this

Nedbank. I can not understand how you train your staff today. Surely the difference between debits and credits would give you your balance. Please explain this to Jerodie Pillay, Sunitha Roopnunan, Boitumelo Thetswe and Burton Pillay. On the.......... last month, after my Housing loan monthly repayment amount was processed several times. Yes that is correct. Not once but several times. This caused me to request that my complex levy debit order be returned. This also ended up being processed twice. I also noticed that the balance left in my housing loan account of access funds paid into my housing loan account changed over the next three days from a surplus of almost R 4 000 to a mere R 1 200. In order to proof this I had to request housing loan statements from Nedbank as they also do not provide you with a report of your debits and credits as well as a balance due on your internet banking app. I provided all the documentation to my Personal banker requesting her to refer this matter to the housing loan department for correction. This request was done on 6 May 2021 as I was admitted to the ICU unit of Wilgers hospital during April 2021. All the above persons mentioned still can not see any problem with my account or are unwilling to assist me. Having been a client of Nedbank for 51 years and been in banking myself I ask you please open the eyes of your staff so they can trace where these funds disappeared to and correct the balance of surplus funds in my housing loan account. Nedbank. I believe that this type of service should not be tolerated by you.
