Debited after cancellation

We cancelled our subscription with Zone fitness on the 21st of December 2015, we were told by Chris that the last debit order pay day was December 1st, 2015, and we would not pay in January 2016, and on our cancellation slip, he had written this.<br> We were debited on January 1st, 2016.<br> I called on the 2nd, and was told the manager would be in on Monday. I called and emailed Monday the 5th of Jan 2016, and Frikkie spoke to my husband to say, if it wasn't paid by Friday, to call back. Today (the 12th of Jan 2016) I have called 5 times, spoken to the lady at reception (who did not know Tracey's email at your company) and gave me Tracey's email 3 times, which were incorrect email addresses, she didn't know Tracey's email address. I eventually got hold of Tracey, and sent her an email, which I had cc'd Frikkie my cancellation slip, and the full story. Tracey said she would get back to me.<br> I have not heard a word since this morning, and am getting frustrated.
