Dismal Service From Credit Card Facilities

I app**** for a credit card on satrurday the 11th of May, on Monday the 13th I received an sms that my application had been approved that I just had to send in some supporting documentation (documents which I had already handed in on saturday), i sent the documentation immediately and was called later on that day by someone asking to verify my details. During that call we were cut off and I have since tried to call back (was on hold for over an hour), I have walked into a bank branch twice, i have called customer care. I have sent an email with other numbers for them to call me on if for some reason they cannot reach me on my cellphone...

Till today the 16th, I still havent received this call and therefore still havent been verified. Im irritated because this seems like such an archaic process. Also... I have done everything in my power to speed it along and i feel the customer service has been dismal. Why can i not be verified within a branch? Why can i not make a call to be verified? If you need to call me why arent you calling me back promptly. All this is making me second guess even getting this credit card with this particular bank
