Card replacement fee

2 weeks back I thought I had damaged my card and I ordered a card replacement on the banking app but when I went to the ATM I found out it's still working fine. I then cancelled the card order before it was even sent to me. their card replacement fee is also ridiculously expensive. I called the client service and was told that the debit fee of the card will be reversed and the card replacement cancelled. I have been calling since last week to sort this out and the fee is still on my account. I had so much faith in discovery bank the service I am getting now just to cancel a card is so bad.
