Card delivery security issues

I was phoned by a consultant to "align" my cheque and card accounts. I gave the consultant my daytime address for delivery of the new card. I then receive numerous calls from a courier company who fail to identify the company name just say they are phoning on behalf of FNB. It would appear that they have access to my home address and not my delivery address. To say they are rude is an understatement. I then receive 2 sms saying that "Takealot Delivery team will call you to arrange delivery of your credit card" and another saying "CCD Couriers Delivery team will call you to arrange delivery of your credit card" I phoned Premier Banking and It would appear that FNB are not concerned that they are giving home address and not delivery address to the couriers. This opens up a HUGE security risk as people know that you will not be home at a given time. To make matters worse I wonder how many cards have been issued!!!! I am now without an active card as my existing card has been diactivated
