Requested a correct statement still no resolution

On 15 December 2015 I received my Woolworths loan statement. It reflects incorrect figures for example for a loan taken out on 10/10/2014 over 36 months the opening balance is R3030.04 the interest is R59.10 the payment is R1282.08 and the closing balance is R3089.14. I called on 22.12.15 and Nomawethhu advised that the figures that I have on the statement and the figures that she has on her computer are different, She will request a correct statement of account and forward it to me within 3 to 4 business days. I called on 07.01.16 and advised Unathi that I have not received the correct statement, She sent me a statement the incorrect one again. I called again on 07.01.16 and spoke to Laura who also sent me the incorrect statement. I called a third time and spoke to Misa. After explaining the situation again she insisted that the statement is correct. Eventually she advised that she will call her team leader. I was on the call with her for 45 minutes, until I eventually hung up as there was no resolution and I was holding most of the time. Please could someone correct my December statement of account and send me a copy.
