Discovery Bank is the worst bank to deal with!!

This is the worst bank I could ever deal with. I sent them an email over 6 months ago and advised them to close my bank account. I got a consultant to call me, which he did and I was advised that my bank account was closed. To this date, my account is still open and accumulating the costs which I cant afford, therefore I wanted to close the account. I have been sending them numerous emails and to date no one has contacted me. I refuse to pay any bank charges as this is not my fault!
