Incorrect account balance: SAB ****** a consumer 132k

I am disgusted by their poor service and not prioritising peoples queries. SAB claims that we owe them over 100k debt of which the money was paid in April. The bank teller duplicated the deposit by mistake and one payment was reversed. SAB claims that both deposit were reversed but can only confirm the date of reversal of one deposit but not the other. The bank manager even went as far as showing me their bank statement and have sent the same copy to them as proof that the funds is in their account but no one is taking accountability to resolve query. Not even the managers ,Sanjay.Naamdhew, Portia Manci, ****chka Venter to name a few. Don't even know why they have titles of Credit Managers. The customer care TL , Lebo advised me last week that the query has been escalated. Last Friday another lady by the name of Hlengiwe , said she will provide feedback on Monday but until today no one contacted me.

I Need FEEDBACK PLEASE and stop robbing the poor.
