Disgusted business client

I was involved in an incident where my vehicle was broken into at Embury college and my bags were ******. When i returned to my vehicle and noticed what happened i immediately tried contacting FNB numerous of times to block all my cards but everytime i inserted my ID number the calls were either getting cut off or i was put on hold indefinetly. 15 minutes thereafter i started receiving withdrawal sms's, R8000 and R4000 i finally had to contact the kloof branch and harshly request them to block my cards and the usuall only the account holder can call and at that time they want to do a security check, how dum and inefficent are they. My concern was having all my electronics like my macbook, ipad in my bag and they are all linked having your passwords etc saved so i am unsure how they could have got my pins. Minutes later I went to florida road ATM thats where 1 transaction took place and asked for help to view their cameras and asked to be assisted and they refused to give me any info. I lodged an investigation to recover my money cos if my calls where answered my cards would have been blocked in time bt due to my calls being rejected i lost R12000.00. FNB refuse to reimburse me.
