insurance cancellation

I was so frustrated and shocked to receive this sms from Hollard insurance <br> Please remember that the premium of R165.00 for your Game Cellular Insurance policy GMPOL*** will be debited on 2016-02-29. For queries contact ***.Hollard<br> <br> after all I bought the phone from Game store on a Friday and took it back on Monday because it was faulty I cancelled the insurance as well and they refunded me policy activation fee and I pleaded with them never debit my account since the phone is no longer on my position i will not appreciate if any money is debited from my account on the 29th
