Debit Card Dispute

I have written numerous complaints on HelloPeter in hope of my query being resolved. If you look at my previous reviews, you'll notice that I have been trying for a couple months to get my debit dispute rectified. Long story short. I have booked a holiday for March through STA Travel. Due to the lockdown I was unable to go and they have now filed for bankruptcy. I have all emails with STA Travel requesting the refund long before they filed for bankruptcy. I have submitted my dispute form many times to FNB with no reply. I have even have references for my follow ups and I tried calling the bank with no help. I need assistance urgently as now I'm very unhappy with the service. Why should the customer follow so many times? Isn't the bank there to assist me but I must still do the chasing. Terrible service. If there was an option to give 1 star I would chose that.
