Account Problem

i opened the account online everything was approved went to the branch they gave me the card ,i used the card but like after few weeks got a call saying the was mistake need to bring my payslips or bank no statement . That was good it's their faulty but it's fine yesterday decided to bring the 3 months bank statement ,i have to wait there for more than 30 minutes because the lady was busy with the consultant on the phone ,and the consultant was busy asking stupid questions i filled on the form when i was applying for the card ,never got so ****ed in my life .<br> My understanding was for me to give them the bank statement and that's i can't take that process that's why i decided to leave. Can you guys cancel the card cause i don't have that time to wait for an hour .
