Very unhappy customer with FNB at this point.

I am unhappy with the service I am receiving from FNB - someone went onto my internet banking on the 21.05.22 and I called FNB on Sunday and I was advised to call Old Mutual, which Old Mutual was suprised as to why was I referred to them. Then Monday the 23.05.22 same thing happened whereby someone went onto my FNB internet banking. I called and I was advised that the account will be blocked and I must go to the branch to unblock the account. I went to Jabulani Mall, and they were offline and went back on Tuesday the 24th, and account was unblocked and I was given a new card. Then I was advised to call Call Centre to reset password which I did but the App is blocked now on the phone I am using. I received a message on the 25th May that the investigators tried to get hold of me I must call back. I called this morning from 8h08 - and I had to drop off as I waited for someone to answer for almost 2 hours, 30 minutes then I used another number. Now I am told that the case has been closed because I did not answer my phone yesterday. The lady said she will put me through 011 number and it went off, I am trying to call that number it keeps on disconnecting. I am really not happy. I was charged R120 for re-issuing of a card.
