Confused Bank!!!

After having to run to the bank everyday for almost 2 week, because the staff kept asking me to come in and sign documents,assuring me that my credit card was approved. Today i get told that it has been declined by head office and they don't know why - I had to keep calling them by the way - they will not call me on their own with feedback until i call to find out whats going on. My initial complaint was on Friday the 20th November and until date this *********** bank has not contacted me yet. They have put me more in debt than anything else, from running to the bank, to phone calls, to having to get emergency money on interest due to their false promises. Their service is pathetic and i would never recommend them. There are never willing to assist you. And i cannot understand how they can approve everything, issue me with a card, make me come in 100 times to sign documents and tell me on the last day that i went in that the card will be active in 48hours, and 5 days later when i had to call to find out whats going on they advise me its declined. Pathetic. They have kept me from going to a bank that will assist me in the first place due to their incompetency and false promises
