ATM retained my cash

I deposited cash at Capitec atm but was unsuccessful and my money was not returned. The ATM gave an error message after money was taken but gave me an error message advicing unsuccessful. I then reported the matter immediately to Capitec branch in village square Mall. I was then assisted and the ATM guys were called. I was advised that it would take 7days for me to be reimbursed. After 7 days there was no feedback given regarding my report and money that was not returned. I then went back to Capitec bank and asked to speak to a manager of which was advised again that it could take up to 14 days of which I waited another 14days and was also advised the guys who load the ATM will be in touch with me. It's now the 12November 2018 and still no feedback was given nor have I received my money back. I am really upset with the poor service I got from Capitec bank.
