FNB *****s itself with CCD

How can FNB use an utterly useless courier service (CCD Couriers) to deliver replacement credit cards to customers. I collected my cards from the bank branch in the past, and that was fine. Now CCD ring me repeatedly for 5 seconds and then disconnect, or say nothing when you answer, and then disconnect They sent me an email to phone their number. You only get an eternal announcement that you are in a waiting queue with no promises of an answer. There are a lot of other available guys who are far better than this
