50/50 *****ulent withdrawal

So disappointed, yesterday my wife withdrew money from FNB ATM at Limpopo using my Capitec card and I received two bank notification of same amount withdrew and we're just a minute apart and she only claims to have withdrew R200 once but also another transaction was made of 200 and when I called my bank dy say it shows that one ATM was used.Please tighten ur security because I was about to open an account with you and have my salary paid into your account but dnt want to find my money gone.Sound like if I use that ATM in Limpopo mall in the near future,I will loose all my money especially if I'm making a large withdrawal
