lost card

on the 11 december 2015 i lost my card and my phone,the following day an amount of R12000 was withdrawn from my account in concession of R5000,R2000 and R5000.and R1800 was swiped at a certain cloths shop.so i went and investigated at standard bank.waterfall branch whereby i was informed that since my girlfriend knows my pin number its possible shes the one who stole my card and the money.so i asked if there isnt a way they can trace atm camera footage to atleast capture the person who used my card.as theres times and date on bank statement,what shock me the most is how can an amount of R120000 just be drawn in one day while my daily limit by then was R5000
