Incorrect charges and mismanagement of homeloan account

Nedbank home loan department or collections failed me!!!I requested that the debit order on my home loan be changed from the last day of the month to mid month(15th)that was June 2026,This request was approved by the bank and debit order went through 15/07 and 14/08.How ever , despite the change being approved,I was subsequently charged interest on the basis that my account was on allegedly in areas.What is particularly concerning is that on several occasions I was informed by their staff that my home loan account was not in arrears,I therefore do not understand how the could suddenly be classified as being in arrears and additional interest changed when I had followed the arrangements provided to me by the bank.Furthermore ,an amount of R600 was debited from my account the 05/09/2026 after visiting the branch the 04/09/2026 .I am extremely concerned about this charge because I had already sought assistance from my local branch to resolve this matter.unfortunatly,the staff member who was supposedly handling my account provided me with incorrect information and,in my view, failed to properly understand or resolve query.I was given assurance that the account was not in not in arrears,only to later discover charges that contradiction what had been told.
