Account declined and no info given

I app**** for an account and only after getting back to me nearly 2 weeks afterwards, I was told it was declined. I couldn't understand this as I have a stable credit score and see no reason for it to be declined. I called the number listed in the email to inquire, however I was told to call a different number. Called the new number and I was AGAIN told to call a different number. Upon calling this number, I was simply told that I need to go in store and inquire about it. I kindly explained to the lady that this is the 3rd number I called and I work from 9 to 7 so I don't have time to go in-store to find out. Her response was simply "Too bad" and she ended the call!!! This is terrible service. Not only was my account declined for a reason I'm still not aware of, but they couldn't even give me a reason why or even be friendly!
