Unauthorised Debit on FNB Account

Good day <br> <br> <br> Please can you return my UIF funds received today from the Bargaining Council, I bank with FNB and advised the branch in Phoenix that I am retrenched & provided them with my retrenchment letter In May already. I have not an income for 3 months & had to borrow money from family for food & rent. Today I received an amount of R4000 that FNB just took all of. My lights will be disconnected, I have 4 kids and another because of the death of my brother 3 months ago. I really need these funds returned as I have NO-other income at all. I will still pay FNB my debt, but in lower amounts, I just need this amount to be returned so I can at least \live"to pay this account instead of dying from a heart attack because of the stress of seeing my kids not having food or lights. I am absolutely stressed out and please require FNB's IMMEDIATE assistance on this matter. I even had to pawn my phone to put food on the table"
