No Sim card 2 weeks after ordering

I ordered a new sim card on 20/1. Delivery was attempted at the incorrect address on 27/1 despite me providing the correct address. 4 phone calls later and still no-one can tell me where it is and when I am going to receive it. I've spoken to 3 different departments today and have been on the phone for more than 35 minutes. Another email being sent to the delivery team. I'm going to cancel. This is just too painful and totally inefficient.
