Account opened without my knowledge

I recently discovered that Discovery Bank had opened a transmission account in my name. The account has been open for several months and has accrued fees. I phoned Discovery Bank and was told that I would need to pay the outstanding fees in order to close the account. I never signed up for this account nor do I want it. It's of absolutely no benefit to me at all. The consultant said that I had approved the opening of the account and that he would go through the records and find proof of my acceptance and then get back to me that afternoon. I never heard anything more from him.

Incidentally, I'm not sure if it's the norm at Discovery Bank for consultants to use profanity in their conversations with clients?
