weird capitec atm

I was at Capitec ATM to withdraw cash, what was strange is that I insert the card in the ATM and on the screen it kept on showing that insert the card. I tried to cancel it but the card did not come out while I was on the way to the Capitec Branch to stop my card I received a notification of an unknown transaction of R500.00 was made in my account. Have I had a airtime I could have made a call to stop my immediately rather than going to the bank . I was astonished because I have been using Capitec for years and I have never experienced such problem I know Capitec bank as the convenient bank and it offers the best service. When I went to the Capitec Branch to tell them what happened hoping they will show me a footage of what happened , again I was shocked to be told that any Capitec ATM doesn't have a camera . That I didn't give my pin and its an ATM fault I think I am entitled to request my money back. As they said they are running a investigation I WANT MY MONEY BACK .
