Unfreeze my account

FNB has placed my account on hold since the 11/09/2019. I was never notified or even given any type of communication regarding this. I found out the day my salary was deposited into my account and I could not transact. When I went to the branch I was told they suspected fruad from money I was transferred by my sister. She has been to the bank to clear up the matter. She emailed all required documents to moetefi at FNB and when we try contact him to unfreeze my account, he does not take my calls. When I went to the FNB branch in Vincent park they told me to wait for a call from FNB 30 days later I'm still waiting for the call or some type of correspondence. I'm struggling every day as I have no money and no one at FNB is willing to assist. I was led to believe the matter would be resolved in 7 days maximum but 30 days later and my account is still frozen. This is not fair as I don't even have money to buy food for my children I'm struggling day in and day out and no one seems to care at the bank. Please unfreeze my account
