Discovery failure

I called discovery Bank a very long time ago In order to cancel my bank account with them as I could not afford the monthly charges for the account. I was told by the consultant that the account wouldnt be canceled immediately and that someone from the bank would call me to cancel this. Since then which was about 5 months ago I still have not received a phone call to get the account canceled but received a email stating that the account won't be closed with NO apparent reason... Still haven't received a call regarding this cancelation and I won't be liable for the rediculous monthly charges. I want this account closed that's all!
