Still waiting on response about replacement cards

It seems FNB have decided to deliver our replacement credit cards, although we didn't request this as it costs extra, and without notifying us. Additionally instead of confirming delivery information with us they instead have the courier company make phishing-style phone calls to me. We were provided with no information we could use to verify the claimed identity of these callers. Furthermore it isn't clear whether their intent is to deliver all the family cards to me or they want me to collect preferred delivery addresses.
