NO RESPONSE ON CREDIT CARD AFTER ONE MONTH

I have app**** for a credit card on 21 November 2015. The application was done and I have send in my documents before expiry date. I have accepted the quotation and everything. Since the 9 December I am still waiting for them to tell me to collect my credit card at the branch. On Friday ( 18 December) I phoned and they said they must reactivate it because they have not worked through my supporting documents. The they said I will hear from them within 24 hours. So today still no response. So again I phoned. The guy told me he is going to escalate it. I do not have time for waiting and waiting and waiting. Because I have done everything within my time frame. Can you please just tell me what is going on with this application. At first with application they have told me that I will wait 9 - 12 working days. And look where we are now?? If I did not phone nothing would have been sorted. SO I am fed up phoning and no one can help me.
