Lack of Feedback

I was approached by one of the sales people at Nedbank as I was pre-approved for a credit card so I agreed to apply for one, that was around the 3rd of November. I followed all the prompts and sent them what they needed. I have been calling regularly and keep getting told the same thing, nobody can tell me how long this process will take. My husband got approved and received his card within the same week with FNB, why is Nedbank taking so long to 'approve' me if they are the ones who called me to take a card in the first place?
