FNB lost or stole my credit card

FNB has zero service delivery now. My card was lost and I waited now over 7 days with no sign of the card. I called several times and they dropped my call. I went to the bank and they told me to call CCD couriers. I called the couriers and they don't seem to exist because their phone lines and emails are down. This is insane! It's like the bank itself is de*****ing me! I want answers and I want my bank card ASAP!??
