STANDARD REFUSES TO HONOUR CREDIT CARD CONTRACT

I was approved for a Standard Bank Credit Card in the beginning of April. I was given the paperwork to sign for my credit card and was to told it will arrive in 5 to 7 working days. Two weeks passed I heard nothing. I went to enquiries and asked when my card would arrive. They said they had no record of my card being issued on their system. The lady went to have a brief conversation with the consultant and he said there has been an glitch in their system he has written to the credit department to notify them that the credit card was indeed approved. They then answered him and confirmed that the credit card has been approved and will be issued in 5 to 7 working days. The bank e mailed me saying that there was an error in their system but not to worry the credit department has again approved the card and it will be here in 5 to 7 days. Again time passed and I heard nothing again I went to enquiries again sorry no credit card has been issued. Now its declined how? I am sitting with the signed paperwork!!!! I want this fixed I want Standerdbank to honour their contract. Otherwise my next letter will be to the Reserve Bank! Honour the contract you made. Its a written agreement!!!!
