Capitec Bank - Increasing Settlement amount from

Sometime in 2012, I took a sum of R100,000 from capitec, and been servicing since and on 27/07/2015 I called Capitec bank online and was given a settlement figure but was advised to go to branch, to be able to confirm it, on 29/07/15 I took leave and went to the Capitec Bank Randburg Square and was issued a settlement letter quoting an amount payable of R22673 and advised it was valid for 7 days, and on the 4/08/15 which was the 6 day I realized I misplaced the letter issued and took leave went to 14 Avenue branch, when to my dismay was told the settlement is R23116 which is almost R600 more than what was confirmed, in querying this was send from pile to post, eventually directed to Randburg as they might have a copy, which they didn't, and called call centre who also seemed clueless and no standard operating process as they were busy telling me the letter is valid for 5 days contradicting their branches, it a waste of time and cheating at it best, scrupulous operation and worse when asked if their system cant given at least a copy was told their system doesn't have audit trail. Their call centre agents are rude and cruel.
