Capitec Spark ATM Half requested amount dispensed from ATM

On the 01 September 2017, I went to a Capitec ATM at the Eskort Bacon Factory to make a withdrawal with my Capitec Savings Card. I tried to withdraw R1000, the ATM only dispensed R500 only but the receipt came out written that I withdrew R1000. I immediately called Capitec customer service and was told the money should reverse within 48 hours. After 48 hours I went to a Capitec Branch in Estcourt and logged a query where I was informed that this query will take 30 days to investigate and they will call me for feedback. After 30 days there was no response from Capitec. I returned to the bank and was told the investigation was so ongoing, I must wait for a call. I then received an sms a few days later letting me know that my withdrawal dispute was unsuccessful. No reasons or how the investigation was conducted. I called Capitec Customer services and was told nothing can be done they will be closing the query. As a Capitec Customer I am unhappy with the manner Capitec is treating my loss of funds, they don't seem to care. How must I trust them as much bank when they don't have my best interest at heart? In this period Capitec told me spark is not their responsibility but I saw the capitec sign I did not know that spark is separate from Capitec. Then when I request to talk to management I get told they will give me the same feedback. I feel I was ****** of R500 by Capitec and was treated badly with no care of my loss. The same incident happened to my husband who deducted money before me and he also got half the money he withdrew at the same atm moments before me and another gentlemen. When I went to Capitec Branch I was told and shown that there were a number of thw same complaints regarding the same ATM. Please help me get my money back.
