FNB is struggling to bank!

I app**** for a FNB Gold Credit card, which they approved. I then took a day off from work and went into their bank in Paarl to go and sort out all my bank accounts. I specifically asked the guy if they need anything else from me regarding my credit card application and he said no it will be delivered in 5 days. They tried to contact me at work, and as I am a teacher, I specifically told them to please phone me after 14:00. Then they just send this automatic sms saying they can't reach me and that I should phone this number. So I did and they said that a call would be placed in my name and they will get back to me. Same story again! I went to their Paarl branch AGAIN and told the girl about the automatic sms that I got, then she just phoned that number!! They then emailed me the contract which I have to send back within 5 working days. I cant email them because their mailbox is full!!!! And now the five days expired and I am back to square 1! Please sort this out!
