Cell C
Why are you still debiting my account

Hi, I have sent letter & emailed you of cancellation of cell number 0846087521 in november 2012 to cancel my Cellc contract, you sent me an sms saying it has been cancelled, but you are still debiting my account. I want my money put back in my account that you have been debitting, after i sent you cancellation letter.
This is the last time i ask for it to be cancel, if i get no joy from this, i will take it further.
