FNB CREDIT DEPARTMENT BAD SERVICE

I app**** for an FNB Credit Card on 21 October 2015. On the same day I submitted the required supporting documents. They said that after receiving the supporting documents it takes up to 5 working days for the credit card application to be processed. I followed up at the end of October 2015 and was informed that they require more supporting documents although no communication was made with me. On the system it states that they endeavoured to contact me on 29 and 30 October 2015, Even when I explained that I never received a call or a miss call from them, I was still required to wait. It is now 6 November 2015 and I have still not received any quotation from FNB or a call to explain what is going on. It is recorded that I am required to follow up with them and send correspondence to them, but there is no service whatsoever. I am a very displeased client. On a previous occasion I tried to apply for a credit card and later gave up because it was just taking too long. I need answers FNB
