FNB not looking after clients

I've had ********** transactions going off on my bank card. I stopped the card and app**** for a new card. Received the new card, but the transactions that was marked still not resolved. It already happend on the 12th of July 2021. If you phone the ***** line you are put on hold. I was on the line for more than an hour without speaking to anyone. Private banker on app I was waiting for a response for 2 hours with no joy. Emails was send and no response
