FNB *****

My account has been *****ed, i recieved an sms around 4:12 am on sunday(05.05.2019) and in the morning around 8am i called fnb to notify them of the ***** transaction, even worse its an international transaction , so they blocked the card and said i should get a new card in 3-5 working days and they also told me that an investigator will contact me shortly regarding the matter. So on monday(06.05.2019) i called again to find out when will the investigator contact me regarding the matter and they tell me to wait for 5-7 working days for thr phone call. So can fnb make me understand how am i to get to work and buy food for my kids when all the money i need is gone and i must wait for the 15th to get a call? As a single parent every cent counts so when i lose money i need to use to get to work how must my kids survice? if i dont get any assistance i will even take this to the bank omburds till i get my money back.
