Incorrect billing

On the 9th March 2021, I complained to FNB about delivery my new bank card. They called me and told they were going to deliver the card and apologise about the delay. I noticed on my bank statement they charged me Replacement card fee of R120, but they know I never received the card in the first place. I told the consultant I deal on the 16th March about the fee. And told me he was reversing it until today they have reversed the fee.
