Unresolved query / bad service .

Been on the phone and into the branch at Balfour. They are unable to correct the minimum payment to be debited from my account. I never agreed to pay back a fixed amount of R2700.00 on an outstanding amount of R7050.00. Three reference number, ***4 / ***8 / ***0 employees / Chatlotte, Dudu/ Leonie/ thokozani/ lunga. 5days later and an email to the client care department. they have not resolved ANYTHING. they simply keep transferring you to another department. Waiting for Dudu's team leader to contact me, day 2 today and still no call back.
