I canceled but still get statements

I'll keep this simple :<br> I cancelled over a month ago , I submitted my form via email as requested . I didn't get any communication that the account was closed, but it did get removed from my Fnb online profile , so I assumed the account was closed . But in fact not only did they not contact me , they haven't refunded my positive balance and they are still charging me ! I just received my statement today, it looks like my card fee went off my positive balance even through I cancelled before it was due . This is complete incompetence. No wonder I cancelled.
