Worst customer service and after sales service ever

I am putting this on here because even a complain on the FNB site doesnt work. about two weeks ago Fnb contacted me and offered me a credit card. I said yes and they arranged delivery. I got the usual sms that says delivery will be before 5pm. No delivery. I phoned and again they arranged delivery, again no delivery. A week later a phoned fnb to complain about the card that has not been delivered. I cancelled the card (ps the card was already loaded on my profile). Three days ago FNB contacted me to ask where must the card (that i already cancelled) must be delivered to. I explained to the lady the situation. She apologised. I gave them another chance and took the card. The card was delivered the next day. Yesterday is signed on to my fnb online banking, to my suprise, no credit card loaded. I phoned them, and the ladies response was that the application was not completed. Said that i wanted to use the card still that same day, she said i cant because it takes 24 to 48 hours to load the money on the card. At that very moment i cancelled the card 'again'. FNB is very unprofessional and extremely ***********. They offered me the card but yet they cant seem to delivered professional customer service. I am not angry, just disappointed that there people in this world that has a job but cant execute it and then there are others that is looking for a job to feed their family.
