iStore Card - Cancellation

I took out an istore card about a year ago. I had issues with the way the card was sold to me where standard bank **** about the interest rate and stated they reserved the right to change the contract at anytime. We resolved that issue and they allowed me to keep the rate on the purchase that was already made but any new purchases would take on a new rate ( Very TCF of them....not) and I continued with the card. I app**** for the card online as this was made to be easier as I cannot get to a bank to do any of my banking. I was assured i would be able to interact online or via emails when doing anything on this card. I have paid the card up and requiure assistance in cancelling the card becuase i dont agree with the chrages process, now i am being forced to go into a branch to get this done which i cannot do and migh lose production time at my current job. I have had one of the worst experiences with standard bank customer service and product offering. They are not truthful and do not make anything easy for the consumer. I understand the charge is a part of their offering to cover their "costs" but i dont want anything further to do with them. My next homeloan will also be taken to another bank
