No card received

I opened a FNB Cheque account. My card was to be delivered. I was informed that they will deliver the next day. I had to ask boss to stay in the office that day. Nobody delivered my card. After a number of calls I was informed that the courier company was Hi-Jacked and my card was ******. 3 weeks later and not one person from FNB contact me with regards to my new card or when it will be delivered. I spoke to a number of people today and not one can tell me if my card's at the courier company. The same courier company they used before informed me that they have not received a new card from the BANK. The bank says they sent it. Should I just stay with my old back. I moved as my company used FNB however all I get's bad service
