Suspension of account

I have two accounts with FNB, so on the 4th of May fnb ***** sent me an email, which I was not aware of because don't receive important emails. So normally with FNB I have a savings account where I can transfer between accounts. Now my debit orders are due I can't transfer to my account or withdraw for transport to go to work. Just because someone sent me money using my initials and surname as the sender and the reference is still my initials and surname by the way the sender used fnb app to me why can't they contact the sender instead of suspendeding my account and ask me for the proof of payment. Since 1st of May 2026 to date the ***** department is doing nothing about this!!! I need my money guys IS THIS FAIR???
