Unhappy customer

My name is N Singh.a consultant called me and we did the application over the phone.I was PRE APPROVED of the STORE CARD and was EVEN given a CREDIT LIMIT..WAS THEN asked to send through BANK STATEMENTS WHICH I did.kept calling them for feedback.it took 6 DAYS to receive feedback saying application was unsuccessful.very disappointed and totally confused how this could be.would like the head of the financial services to contact me with reason .
