Zero customer service at FNB

I was charged insufficient fee of R115 on the 1st Nov when I had enough funds available to cover my debits, I noticed that 2 of my debit orders went through twice and were then credited so went to Broadacres brand to query the unusual activity. An unhelpful person called Thabiso wouldn't even give me a ticket to see a consultant for assistance, She blocked me at the entrance and in front of everyone at the branch asked me to relate my issue. There I was thinking it was so she could issue me a ticket but NO it was so she could tell me "We had system issues over the weekend, but I was charged because the account was mine." which is just wild!!!!! She said secure chat can help me not the branch. I expressed my frustrations with secure chat and she said well the account is mine once again which I still don't understand HOW the bank having system issues relates to banking errors and me having to absorb a random fee because I am an account holder! So am online now with secure chat and 3 consultants later zero assistance, just bouncing around this is the worst platform that just needs to be done away with.
