FNB service is pathetic

I had an offer on my banking app for a second credit card at FNB. I then clicked the link to find out they upgraded my credit card. I immediately called them to cancel the upgrade. The couriers called me the next day for delivery of my new credit card. Which I found strange, As when I app**** the first time it took almost two weeks to deliver. I declined the new card as it’s not what I wanted. It’s been over 30 days with no correspondence from FNB. My credit card is still not sorted out. It’s the worst service from FNB. I called the call centre to be transferred from person to person before being cut off. I have sent several emails with no reply. I can not believe the pathetic service.
