STD Bank *****ing rom us on refusal to cancel creditcards

I keep requesting that this card be cancelled however I get told every time that there is an overdue amount. I have set up a debit order to go through for the amount I was told was due and the amount went off successfully but every time I request the card to be cancelled I get told I must phone at the end of the month to have it cancelled and when I phone to have it cancelled I get told, O !!!!you have an over due amount on your card, service fees....for what service!!!! as you are not giving me any service and am not using the card, how does it really work.....After the "fees amount" went off on the 25th of August I phoned to have the card cancelled and I was told to phone at the end of the month to have it cancelled and I am phoning but get told the card cant be cancelled because there are fees .....seriously!!!!! please just cancel the card as I have no use for it and will not be paying this card any longer as it is your agents fault that the card is yet to be cancelled. I would rather get it from another banking institution because now I am paying for something I don't want. Also the call center agent are clueless and to top it all off rude.....I refuse to deal with people like that. please just have the card cancelled as you do not even send me statements. please make sure this card has been cancelled as I refuse to pay anything on it again. ********** ********** 32.
