NO RESPONSE REGARDING NEW CREDIT CARD ACCOUNT

App**** online for a new Credit Card more than 2 weeks ago and almost instantly got the text informing me that all had been approved via App. Gave the delivery details via the app for delivery of the credit card but have heard nothing since. The account has even been added to my online banking profile and a card number reflecting under the account but no balance available. I lodged a general enquiry via the FNB website, and received a Query number and told I would hear back in 48 hrs. Still nothing. Then emailed the card department more than a week ago, still no response. What is going on with my new credit card account? When will it be delivered?
