CCD Couriers insistently phoning me with wrong numbers

After they delivered my diners club card, as they were supposed to, I have been getting phoned by them 2 - 3 times per day. Mostly wrong numbers (asking me if I'm people I've never heard of), when I ask them to remove my number from that person's profile, I get promised that it was removed, only to be phoned again minutes later asking for the same mysterious person. Yesterday they phoned me asking me to confirm my delivery address, when I said I'd already received my card the lady insisted this was a second card that needed to be delivered, only to find out there is no second card. Please sort your admin out. Take my number off profiles that don't belong to me and stop harassing me with your phone calls!!!!!
