Worst Customer Service

This month FNB connect debited my bank account for the amount of R333.50 (top-up Max). The 14th of January 2023 and the 25 January 2023. When I phoned earlier I had a call logged and was given a reference number 735551. Today the 27 January 2023 I phoned again and spoke to an Agent Vuyani Mabaso (who does not have good customer service etiquette). I wonder where FNB gets these people from. Long story short, my issue is not resolved and FNB is busy sending me invoices for the debit which they did on 25 January 2023.
