Still paying for cancelled contract

<p>Good Day</p> <p> </p> <p>I am writing on behalf of my mother. Every few weeks she has to call you to query why she is still being charged for a contract that she cancelled on the 24th of August 2016. Each time they she is assured that it will not happen again. But every month it does. PLEASE cancel number " ********** 578" immediatelly and credit her the amounts she has been paying since. She also called recently to cancel the contract for number " ********** 898" which expires end of February 2017. I trust both of these contracts will be successfully cancelled and that she will no longer be charged for them. Thank you</p>
