Victim of *****

So yesterday I went to Cellc to go have an upgrade done, I couldn’t have it done as my ID number had been tagged for *****. I was then given the number to the South African ***** prevention line, I was told by them to contact fnb, their numbers never go through if I get one it goes to the wrong department, I get another number and when put through it gets cancelled. I need this sorted out and I don’t know who to call or what to do. I haven’t used this account in many years and I am a victim of ***** and not receiving any help, I’ve been on the phone for the past hour and a half with fnb and haven’t gotten any help at all.
