********** activity on my cheque account not resolved

Someone bought online **********ly on my cheque account back in the first Friday of Feb 2021. The person bought something for more than a R1000 of my hard earned money. I immediately reported the incident. My card was cancelled and I was issued with a new card. I was told there would be an investigation. I have tried to follow up, each time I am told to call their ***** line which is not user friendly. I have been a loyal client of FNB for more than twenty years now, but I am exploring my options now. This is really bad customer service.
